But then you end up with the source_dir lying in the parent of target_dir. My
intension was something like having to move the /usr or something to
/new_user.
Anyway, an easier way to state the same thing would be:
(cd /source_dir/..; tar -cf source_dir)|(cd /target_dir; tar -xf -)
Hmm... Maybe this will work better...
(cd /source_dir; find -maxdepth 1 | grep -v '^\.$' | xargs tar -cf - )|(cd
/target_dir; tar -xf -)
Another tip - If you intend to move your / to somewhere else - completely, if
you're not careful, you'll end up in a loop - because a tar of the / to
somewhere else will include the target as well...
What I normally do to move / is:
1. Mecome single user - init 1
2. unmount everything possible. - proc etc.
3. ls / > /files
4. edit /files and remove anything that isn't to be moved - like a mounted
/usr or the new / mount point.
5. (cd /; tar -cf - `cat /files` )|(cd /new_root; tar -xf -)
Hmmm... I guess there are a lot of ways of doing this. This is just how I do
it normally. (Yep ! Like I normally keep giving my / some exercise :)
cheers,
Faisal.
