The 9pi image is very standard Plan 9. Libraries, command binaries
and kernel are all built from distribution sources with
cd /sys/src && mk install
cd /sys/src/9/bcm && mk install
For the first, you need to link with the '-f' flag to get hardware
floating point. That could be done by editing mkfiles, but since I
build for other arm systems from the same sources, I do it by setting
up aliases in my shell environment before running mk -
fn 5l { /$cputype/bin/5l -f $* }
fn pcc { /$cputype/bin/pcc -f $* }
The rest of the image is the same as the standard distribution for any
architecture, with x86 binaries and libraries removed, and these small
changes in config files to make an easier introduction for new users
running as 'glenda':
1. The /rc/bin/termrc.local script will optionally start up networking
using the command defined in cmdline.txt variable ipconfig=
2. The /usr/glenda/bin/rc/riostart script adds a console output window
to prevent console messages from messing up the rio desktop
3. The /rc/bin/replica/pull script filters x86 binaries from the update
log, so the replica/pull command won't add them all in again
