John,

There are no problems using CentOS.  There may be some issues with 
autoconf on FC9.  FC8 worked fine.  A 32bit host system works better 
than a 64bit host (for the build environment).

2.5 kernel?  Those were the beta ones before 2.6 came out!  Dang that's 
old.

Everything is accurate with Chris's instructions until the end.  See 
more notes inline...

No need to pull the CF card!  Simply issue this command:

mount -o remount,rw /oldroot/cdrom

Then use scp to copy the new files into the /oldroot/cdrom/os directory. 
  Note:  Do NOT delete your current images.  Reboot first then remove 
the old files.

Multiple astlinux-XXX.run, astlinux-XXX.run.conf, astlinux-XXX.run.sha1 
files can remain in the 'os' directory.  The newest one is used unless a 
'ver' file exists which can be used to specify the version to use.  (the 
format for the ver file is astlinux-XXX).

Also with versions after 1895, you can specify astkd=auto and 
asturw=auto.  If you used genkd and genunion to create your file 
systems, the correct file system labels will exist and be automatically 
detected.  You can test this by typing:

findfs LABEL=ASTKD
findfs LABEL=ASTURW

>> Then copy your new astlinux-trunk-xxxx.run file and its associated .sha1

See above...

This is really why we like the new system and why it's taken so long to 
get a release ready.  It's much easier to upgrade and manage remote 
upgrades.  No need to pull the CF card each time an update is needed.
