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. |

Already solved but waiting for something to finish so here's my version: |
| 13 |
|
| 14 |
#mkdir /mnt/tmp |
| 15 |
#mount -obind / /mnt/tmp |
| 16 |
#cp -a /usr/lib/* /mnt/tmp/usr/lib |
| 17 |
#umount /mnt/tmp |
| 18 |
#rm -r /mnt/tmp |
| 19 |
#umount -l /usr/lib/ |
| 20 |
|
| 21 |
At this point restart as much services as possible is a good idea (but |
| 22 |
not really needed). |
| 23 |
|
| 24 |
The trick is done by "bind" option _not_ binding mounted subdirectory |
| 25 |
(i.e. after step 2 /mnt/tmp/usr/lib should be empty) as opposite of |
| 26 |
"rbind" that bind also all mounted subdirectoryes (and is useful |
| 27 |
sometimes with /dev) |
