From the initrd linuxrc:
# mount shared memory filesystem with a limit of 40GB (for now)
test -d /dev/shm || mkdir /dev/shm
echo -n "Mounting SHM FS on /dev/shm"
mount -t shm -o size=40g shmfs /dev/shm && print_status success ||
print_status


Oops that's not 40MB as you can see it's 40GB :-)
I must have been somewhere else when I wrote that piece of code.
I'll correct that to 40megs.

If we say that we need a minimum of 64 MB of RAM we have to make sure
that the machine has some RAM left to start some programs. Even more
in the case when we have no swap.

Heiko can you try a full install and give use the maximum SHMFS
footprint in this case so we see some numbers to talk about.
Maybe we should document the basis memory footprint and also the one
for each package so the user can calculate if he needs more than 64MB
of RAM.

BTW patches to calculate the limit based on the amount of installed
RAM are more than welcome ;-)

Agreed.
