I have to do the whole system cleanup, deleting and recreating all partitions.
I'm wondering if I could simply tar all my / (excluding proc, sys and mnt) into archive and then untar it into clear partition from livecd after this full cleanup, reinstall grub and have my system working as before.
Would it work? If not, what would you recommend?
Probably, same troubles with partitions in system itself? (fstab is the simplest example)
