I have a number of systems with different shm lines in fstab - but which
is correct? - I think they all work, but which is best (and why)?  The
main use I am concerned about is a PXE system with root over nfs where I
am putting the portage tmp and some other stuff in tmpfs for speed.

tmpfs	/dev/shm	tmpfs	defaults		0 0
shm	/dev/shm        tmpfs   nodev,nosuid,noexec     0 0
none	/dev/shm	tmpfs	defaults                0 0

I suspect the middle line is correct.

I have 

shm                     /dev/shm        tmpfs           nodev,nosuid,noexec     
0 0

for ages in fstab. If it is wrong, I am living a lie for years now.

Thanks, the reason I am not sure is I often copy fstab between machines
to speed up configuration, and I suspect the lines with "defaults" trace
back to circa 1989 (my first gentoo - over dialup modem with 7 days of
downloading/compiling on a 200Mhz K6 :) or whenever tmpfs appeared in
the kernel.
