I guess that makes sense.

Hm, yes. However, some kernels have tmpfs support (it's called tmpfs
now; shmfs has been deprecated, and you /do/ have to configure
it in. 2.4 is broken with the shmfs/tmpfs distinction, btw), others
have ramdisk compiled in or as a module, others don't have it at
all, and it all depends on the kernel you are running at that moment.
As soon as you upgrade the kernel things change and you do not
want them to break ...
So, it would be better to mount /run automatically without an
/etc/fstab entry, since it's hard to say what that entry is.
Besides, for a ramdisk, you still need to mkfs a filesystem on
it before mounting it, so it's all special case code anyway.
Confused,
Mike.
