/dev/shm not mounting at boot time{SOLVED MYSTERIOUSLY]

[BenderBendingRodriguez]

cat /etc/fstab (only relevant options shown)

/dev/sda1 /boot ext2 noauto 1 2
/dev/sda5 / btrfs defaults,relatime 0 0
/dev/sda6 /usr btrfs defaults,relatime 1 1
/dev/sda7 /var btrfs defaults,relatime 1 1
/dev/sda8 /tmp btrfs defaults,relatime 1 1
/dev/sda10 /home btrfs defaults,relatime 1 1
/dev/sda9 none swap sw 0 0
#/dev/cdrom /mnt/cdrom auto noauto,ro 0 0
#/dev/fd0 /mnt/floppy auto noauto 0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
# use almost no memory if not populated with files)
shm /dev/shm tmpfs nodev,nosuid 0 0

I can manually mount it with no problems at all. But i have no idea why it doesn't mount automatically since i didn't change anything in any config file.

Hi,

Can you show us your /etc/mtab file?

I need to change it to mysteriously solved since it mounts again. It wasn't mounted earlier as i was checking mtab and also chromium was complaining that /dev/shm is not mounted.
