OK JGC,

I know that Arch Linux don't support these directories as tmpfs or "all
empty" by default, but with these trivial patches to rc-script can
support it.
Not only this is usefull for "tmpfs", maybe for other things.

Ok the FHS recomendations, about /var/run as how to interpret the FHS's
recommendations can lead to different paths:
For example (PATH 1) if we understand that /var/run at startup must be
completely clean, these patches are useful. But (PATH 2 "The current
Arch" ) if we interpret that there should be no files, but there may be
directories.

The number of packets that need to be changed I do not think is problem,
also need not be changed immediately. Maintainers can apply the patch
for the next update when new version is released.

For example, the current rc-script of HAL that you mantain, it check
that the /var/run/hald/ and subdirs are created, but these are always
created by the package. :) Why not do the same with other packages?

Personally it is not something I need, just occurred to me that it might
be a good idea, I take my time researching what packages were needed,
and I did.
Sorry if I bothered.

Thanks for your time.

(and sorry for my bad english)
