RE: [cobalt-developers] CMU and Tar to transfer sites from one Raq3to another

[ProServe - Peter Batenburg <peter@xxxxxxxxxxx>]

Hi,

AFAIK linux stores usernames & groups as numbers. And if the users &
groups are recreated, they will get new numbers. So your method would not
work. Maybe rsync does something to fix this? Some people have insights in
this?

With kind regards,
