<span style="font-size: 10pt">Since it is what many mail clients do it might be helpful for other people to have this.
As for me, I like to have all my outgoing mails automatically saved in a </span><span style="font-size: 10pt"><i>Sent</i></span><span style="font-size: 10pt"> directory, so that’s what I want to do.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">There are multiple ways to do this.
I want to present a very simple way without sending your mail to yourself or something like that.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Outgoing mail is processed via
</span><span style="font-size: 10pt"><tt>upas/send</tt></span><span style="font-size: 10pt">
or
</span><span style="font-size: 10pt"><tt>/mail/box/$user/pipefrom</tt></span><span style="font-size: 10pt">,
if that exists.
We use this feature to build or own little filter script for outgoing mails.

<span style="font-size: 10pt">The script itself is very simple.
We just need a temporary place to store the mail message, then save it in the
</span><span style="font-size: 10pt"><tt>Sent</tt></span><span style="font-size: 10pt">
directory and forward it to the normal send routines:

<span style="font-size: 10pt">Of course you need to create the directory

<span style="font-size: 10pt">The
</span><span style="font-size: 10pt"><tt>Sent</tt></span><span style="font-size: 10pt">

<span style="font-size: 10pt">If you want unauthenticated users to send mails to that directory you need to make this directory world-writable.

<span style="font-size: 10pt">A few weeks ago I removed archlinux from my remaining machine.
I noticed how the new lenovo keyboards aren’t good and the trackpoint is crap.
That’s why I still prefer the Thinkpad T61, even without battery.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Anyways, I’ll try to describe the process of the installation.
The installation itself went according to the FQA, I’ll just add some notes.
</span></p><p style="margin-top: 0; margin-bottom: 0.17in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt"><b>Process
</b></span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">First I had to disable UEFI completely and switch to legacy BIOS.
I know 9front can handle UEFI somehow, but I never got it working on any machine.
To make 9front work with legacy BIOS I had to change the SSD layout from GPT to MBR.
This was possible, just remove all partitions and use the command line to create DOS partitions.
Then the SSD was detected as MBR/non-GPT and I could proceed with default installation.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">After installation I needed to get WIFI working.
Thanks to 9front developers I was able to use BSD drivers as documented in the FQA.
In my case I just grabbed the
</span><span style="font-size: 10pt"><tt>iwn-2030</tt></span><span style="font-size: 10pt">
drivers, placed them in
</span><span style="font-size: 10pt"><tt>/lib/firmware</tt></span><span style="font-size: 10pt">
and built the kernel from scratch.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Enabling ACPI in the
</span><span style="font-size: 10pt"><tt>plan9.ini</tt></span><span style="font-size: 10pt">
and starting
</span><span style="font-size: 10pt"><tt>aux/acpi</tt></span><span style="font-size: 10pt">
went without errors, only
</span><span style="font-size: 10pt"><tt>bad opcode</tt></span><span style="font-size: 10pt">
warnings showed up.
Still, everything works as expected, so I didn’t investigate further.
</span></p><p style="margin-top: 0; margin-bottom: 0.17in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt"><b>Issues and Troubleshooting
</b></span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">I had exactly
</span><span style="font-size: 10pt"><b>two</b></span><span style="font-size: 10pt">
issues.
The first is the
</span><span style="font-size: 10pt"><tt>bad opcode</tt></span><span style="font-size: 10pt">
as described earlier.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">The second is a big surprise.
Backlight controls work out of the box!
I know older machines handle this directly without using the operating system, but this was a modern machine.
Still it worked with only one tradeoff:
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.35in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">It always prints
</span><span style="font-size: 10pt"><i>lapicerrors</i></span><span style="font-size: 10pt">
on the console.
I didn’t find a good way to disable them, so I just added a hidden window in my riostart that just
</span><span style="font-size: 10pt"><tt>cat</tt></span><span style="font-size: 10pt">/dev/kprint
so the errors don’t fill the screen.
</span></p><p style="margin-top: 0; margin-bottom: 0.17in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">

<span style="font-size: 10pt">As a bonus I have a small script that saves me lots of installation time.
I have a server with my $home directory, including some configuration in my
</span><span style="font-size: 10pt"><tt>lib/profile</tt></span><span style="font-size: 10pt">.
On my terminals (laptops) I just work in my $home like it was right there on my machine.

<span style="font-size: 10pt">To make this happen I placed the little script in my terminal’s

<span style="font-size: 10pt">Recently I installed my mail server on 9front. Most of the time I followed the guide in the FQA, but still there are things to explain. In this document I’ll go through the section of the FQA and annotate things.

<span style="font-size: 12pt"><b>9front on Netcup VPS</b></span></p>
<p style="margin-top: 0; margin-bottom: 0.21in"></p>
<p style="margin-top: 0; margin-bottom: 0.21in"></p>
<p style="margin-top: 0; margin-bottom: 0.42in"></p>
<p style="margin-top: 0; margin-bottom: 0.21in"></p>
<p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="margin-top: 0; margin-bottom: 0.50in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Today I installed 9front on a Netcup VPS. Here are some notes if you want to do it yourself.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">I used the smallest VPS option. Currently, that’s “VPS 200 G8”. It costs like 2.69 Euro, but you might be able to find some way to make it cheaper.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">After ordering it might take some time until the server is up and ready.
By default debian was installed in a GPT, we can ignore that.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Before we can install our custom ISO we first must upload it somewhere.
This is done via FTP (you get the access data from the SCP), I used windows default file explorer
(</span><span style="font-size: 10pt"><tt>ftp://user@address</tt></span><span style="font-size: 10pt">,
enter password). Copy the 9front ISO in
</span><span style="font-size: 10pt"><tt>/cdrom</tt></span><span style="font-size: 10pt">.
This will take some time.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Meanwhile you can delete the virtual disk and create a new one. You need your SCP password for this.
This step is necessary to remove the GPT. Of course you could manually reformat the disk, but deleting the disk will save time.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">In the settings you can virtually insert the iso as a DVD and verify the boot order (DVD first).
Start up the machine and switch to the web VNC display.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">At this point you can proceed with the default 9front installation described in the fqa.
Don’t forget to install the MBR and activate the partition.
Otherwise there are no additional special steps besides manually configuring the
</span><span style="font-size: 10pt"><tt>/lib/ndb/local</tt></span><span style="font-size: 10pt">
after installation.
In my case I made an auth server.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Currently it seems to work fine. I installed the machine today, so there might be some issues I didn’t find yet.
</span></p><p style="margin-top: 0; margin-bottom: 0.50in"></p>

<span style="font-size: 10pt">Today I want to share with you, that I use the plan9 distribution “9front” as my main computer.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Of course there are things that are almost impossible to do there, for example: all gamedev related stuff. This is of course an issue, because I am a game developer. I still have my windows machine with relevant tools, so I can still fiddle around with those complex things.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">For gaming I also use my windows machine or some game console. Yes, there are a few games on plan9 systems.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Also most online services use javascript and heavy styling of webpages, so I also use a modern computer with a modern browser. Mothra is fine for doing basic research stuff, but in 2020 it’s almost impossible to actually do things on the web.
</span></p><p style="margin-top: 0; margin-bottom: 0.05in"></p>
<p style="line-height: 1.2em; margin-left: 1.00in; text-indent: 0.00in; margin-right: 1.00in; margin-top: 0; margin-bottom: 0; text-align: justify;">
<span style="font-size: 10pt">Anyways, let me tell you that I don’t really miss anything on plan9. I can write documents, check my email stuff, chat with people, and step by step it becomes more usable. The community is helpful and provides more applications. The system runs stable, the user interface is consistent and good to look at. Colors don’t jump in your eye and want to kill you and there’s catclock(1), our friendly companion.
