Afaik, Ubuntu is already using this.  As a result, I've actually got a
bug against my package submitted because it didn't handle it.   My
package now recreates the directory from the init script if it's
missing, and I'm not really happy about that solution.

I'm not really sure what the right thing to do is.  Maybe the FHS should
be made clear on what you can expect from /var/run.

I guess it would be useful to know what people now put in there.  I know
some daemons just want to have empty directory they can chroot to.
Maybe they should put that somewhere else?  I have no idea what others
are putting there.

Anyway, it would be useful if you didn't have to login on merkel to be
able to see your list.  I suggest you either submit those files to the
BTS, or put it on people.debian.org or something.
