[gentoo-user] /dev/shm and firefox question

[Jean Magnan de Bornier]

Hello all,
I recently installed qemu; when I launch it I get this message:

"You do not have enough space in '/dev/shm' for the 450 MB of QEMU virtual RAM.
To have more space available provided you have enough RAM and swap, do as root:
umount /dev/shm
mount -t tmpfs -o size=466m none /dev/shm"

OK, it works; so in order to avoid doing this every time i added
"size=466m" to the options column of fstab. It seems to work allright but
for the fact that then firefox does not work anymore: I can launch it, but
then it freezes.

And then if I issue by hand these commands, firefox is as usual again!
What am I doing wrong?

Here's my fstab's tmpfs line:
.................................
# 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,noexec,size=466m	0 0
................................

tia,

Well, this was no solution for firefox; looks like there was a corrupt
file in my ~/.mozilla... strange coincidence!

cheers,
