Hi all,
Still experimenting with xen and lvm on fc4.
I've created a mount point, /usr, that is read only, thinking more than
one xen domain could use it.
Even though I've never used it this way, I always (mistakenly?) thought
that /usr could be read only. I've been turning off most services one
by one, and keep making it further, but have yet to successfully boot
completely.
Rather than a clean install, I created it with lvcreate vg0/usr,
mkfs.ext3, mount vg0/usr /mnt, cp -a /usr /mnt, then edited fstab to
create a /usr mount with standard defaults except rw as ro.
I'm not convinced yet that that was the correct way to do this, or
whether my original assumption that /usr could exist as a "read only"
directory was correct.
Yes, /usr can be read-only. That's how my systems normally run.
I do see a problem with your "cp -a /usr /mnt" command. That's going
to create a directory /mnt/usr, and when you try to mount that
filesystem on /usr your original /usr directory tree will now be in
/usr/usr and that will break just about everything.
Try "cd /usr; cp -a . /mnt" instead.
