Re: restoring FC1 to *new* partition from tar archive



It would appear that on May 8, Luciano Miguel Ferreira Rocha did say:

OK I won't worry about sockets... Thanks!

Perhaps so, But I'm also using the tarfiles for an archive...
# split -b 699m tarfile.tgz tarfile.tgz_split_
Then I burn tarfile.tgz_split_aa on one cd-R, tarfile.tgz_split_ab on
the next, etc...

I'm hoping you mean that as long as the source and destination
filesystems have an IDENTICAL /etc/password... I shouldn't worry?
Actually I did use mdk to create the tar from an FC1 filesystem. And I
used mdk to restore it as a complete FC1 filesystem... I'm thinking the
problems would be if I tried to restore it TO the mdk filesystem. (I hope)
