RH5 wants to fsck the root FS. I stopped this with a /fastboot.

/etc/localtime is a link to TZ file in /usr/share/...
I made it a copy.
Turn off /etc/rc.d/rc6.d/K97network or it will disable the
network before root FS is done with.
X server wants to write into /usr/X11R6/lib/X11/xkb/compiled.
I made this a link to /etc/X11/kbd/compiled
Remember your DC will keep appending to log files so have logrotate or something deal with them at regular intervals.
