I'm getting an error message during emerge:
 * configure has detected that the sem_open function is broken.
 * Please ensure that /dev/shm is mounted as a tmpfs with mode 1777.
 * ERROR: dev-lang/python-3.3.5-r1::gentoo failed (configure phase):

my /dev/shm is mounted as 
drwxr-xr-x 17 root root          4020 Oct  3 08:57 shm

and it should be:
drwxrwxrwt  2 root root           100 Sep 29 09:25 shm

I've already change in fstab:
from:
shm			/dev/shm	devtmpfs	nodev,nosuid,noexec	0 0

to:
shm 			/dev/shm  	tmpfs 		defaults,nodev,nosuid,mode=1777 0 0

Is it OK to run:
umount shm
mount shm

This is a remount system, so I want to make sure I'm not making a mistake.
