If you are willing to take the system down for a few minutes, try booting with a copy of knopix or your gentoo livecd, and doing your filesystem mods that way. Then you can be more comfortable with the sanity of your os. after all there is so much important stuff in there. Or maybee drop to single user mode, that may work. -- Your responsibility as a parent is not as great as you might imagine.

michael higgins wrote: Hello, all. Some time ago, I moved my /usr/lib folder to a separate partition to net some space on /. Now, I want to fix my partitions on that second drive, so I've moved all the linux folders to / again. (The /usr/lib files are in a folder called /usr/lib2 for now.) The problem I've come across this time is that so many things are using files in /usr/lib, I can't unmount it. Stopping all services leaves me with my login being the only thing still hanging the umount. So, my question is, does anyone know what will happen if I try to umount -l, remove the /usr/lib mountpoint, and rename /usr/lib2 to /usr/lib? It would seem that there'd be no problem as long as I don't need to log into a new shell? Going the other way wasn't a problem, as I just renamed the old folder and mounted the partition on a new one. Any suggestions appreciated. Already solved but waiting for something to finish so here's my version: #mkdir /mnt/tmp #mount -obind / /mnt/tmp #cp -a /usr/lib/* /mnt/tmp/usr/lib #umount /mnt/tmp #rm -r /mnt/tmp #umount -l /usr/lib/ At this point restart as much services as possible is a good idea (but not really needed). The trick is done by bind option _not_ binding mounted subdirectory (i.e. after step 2 /mnt/tmp/usr/lib should be empty) as opposite of rbind that bind also all mounted subdirectoryes (and is useful sometimes with /dev) -- gentoo-user@gentoo.org mailing list
