I've heard a couple of reports, to the effect that upgrading from 7.0
to 7.2 is quite tricky - much harder than installing 7.2.
What I did for my 7.1 to 7.2 changeover, was take copies of /etc,
install, and then compare and gradually re-config services one by one,
making manual edits where necessary. This was possible because /home
and /usr/local were on separate partitions in my case.
This was my todo list / checklist:
Add the local users and groups back again
Add fstab entries for home, and all the other partitions.
Restore /root from backup (oops: I kept some stuff there too).
Try out Postilion and the rest of /usr/local.
Put /etc/rc.local back.
Put fetchmail config files back.
Configure sendmail again (little change, actually quite painless).
Samba config again.
Add hand-tuned X modes back again.
Put normal mods back into /etc/lilo.conf again.
Re-compile rxvt.
Ditto xcb.
Download and install bug fix rpms (thank god for up2date and cable
modem - 200 MBs of replacements!)
Re-build kernel for CD-RW (re-add my improvements to xconfig Tk
scripts).
Run Samba at boot (use serviceconf to for run level services).
find / -uid 50 -print0 | xargs -0 chown luke
find / -gid 52 -print0 | xargs -0 chgrp kendall
(Last two since new standard RH user and group IDs overlapped existing
owners and groups.)
