Hi Stephen,
The other version was one that would partition the laptop disk
into 'mirrors' of itself.
I do something like this on a server, to be able to boot back into a
known good state if an update ruins the system.
/boot -- 1 I think
In my setup I use two boot partitions (or actually /boot is part of /1
and /2). This is especially useful when doing kernel updates (instead of
installs), like SuSE does.
/1
/2
/home -- 1 I think
Yes, user data is shared. Also share /var/log and /var/spool (and /srv),
but not /var/lib (rpmdb etc). Another proof of how messy /var is...
boot is set up to boot into say /1 the first time, and then the
asyncd
updates /2 to whatever the network says it should be.
I just rsync the known good system to /mnt/backsys (which is /2) before
an update, but then my setup is used to be able to roll back, not
forward :) .
Grub is changed appropriately
In this roll back setup it is also important to adjust /etc/fstab
according to the / partition. It's an integral part of the rsync
scriplet I use. Seems to work flawlessly, but luckily I never had to
rely on it (knock on wood ;) .
Leonard.
