+1 on find, but the comand line should be
find . -depth -print0 | cpio -pvmd0 newroot
otherwise files with spaces in the name can get trashed, and the
permissions on directories may end up wrong.
Thanks for the cpio hint.
Next, how do I persuade the new partition to boot? Do I have to do some
magic with grub? If so, what? Do I cpio the old /boot onto the new,
non-LVM boot partition? or can I use /boot within the new LV?
Everything I read says to put /boot into a non-lvm partition. Does
grub-install from a live CD give me the opportunity to spell out the
right parameters?
I don't want to simply experiment in case I do bad things.
I have no experience with LVM until now.
