+Building Go from source on 9front
+=================================
+
+For building go on 9front its best to leverage ramfs for faster build times.
+It also is reccomended to use the 9legacy bootstrap tars if you lack an existing installation.
+
+First start by downloading and extracting the tar balls:
+
+ ramfs
+ cd /tmp
+ hget http://www.9legacy.org/download/go/go1.14.1-plan9-amd64-bootstrap.tbz | bunzip2 -c | tar x
+ hget https://golang.org/dl/go1.14.7.src.tar.gz | gunzip -c | tar x
+
+Now we will need a place that we want to be our GOROOT, something like /sys/lib/go/amd64-1.14.7 will work.
+Create the destination dir and bind our go source dir in /tmp over it.
+
+ mkdir -p /sys/lib/go/amd64-1.14.7
+ bind -c go /sys/lib/go/amd64-1.14.7
+ # change directories to the new location so GOROOT gets set properly when building
+ cd /sys/lib/go/amd64-1.14.7/src
+ GOROOT_BOOTSTRAP=/tmp/go-plan9-amd64-bootstrap
+ build.rc
+
+After building the tree in /tmp needs to be copied in to the right location.
+
+ unmount /sys/lib/amd64-1.14.7
+ dircp /tmp/go /sys/lib/amd64-1.14.7
+ unmount /tmp
+ # You could also bind the binaries in if you choose
+ cp /sys/lib/amd64-1.14.7/bin/* /amd64/bin
+
