Hi all,
This was discussed within a couple of threads in the last few months,
but I wanted to ask for final clarification before I go ahead with this
(yeah, I know, 'paranoia will destroy ya')...
I'm not afraid of an initramfs any more, but I've decided that I still
just really don't want one, so I'm looking for the safest & simplest way
to merge my separate /usr back into /.
The only thing I'm really unsure of is the optimal method and exact
syntax (ie, trailing slashes? arguments?) for the actual copy of /usr.
Is rsync -a enough for my relatively simple system setup, or would using
any or all of the other options suggested in those threads be
safer/better? Specifically:
-a, or -axAHX, or -apogXx, or -PvasHAX
or should I go with a combined -apogsvxAHPX ?
So, here's the plan, please check me...
1. Boot off of the latest gentoo LiveDVD
2. Mount / and create new /usr directory
mount /dev/sda3 /mnt/gentoo/
mkdir /mnt/gentoo/usr
3. Mount old /usr to be moved/merged
vgscan
vgchange -a y
mount /dev/vg/usr /mnt/gentoo/oldusr
4. Copy /oldusr to /usr
rsync -a? /mnt/gentoo/oldusr/ /mnt/gentoo/usr/
Are the trailing slashes required/important/necessary?
Which arguments should I use?
5. Edit /etc/fstab and comment/remove the /usr line
nano -wc /mnt/gentoo/etc/fstab
#/dev/vg/usr /usr reiserfs noatime 0 0
6. Unmount mounted filesystems
umount /mnt/gentoo/oldusr
umount /mnt/gentoo
7. Reboot into new system
Done?
I'm pretty sure that:
1. There is no need to chroot into the real system during this process,
and
2. I only need to mount / and the old /usr, no need to mount anything
else (/proc, /sys, /var, /home, activating swap, etc)
Correct?
Thanks
