Yes, that's a bug you find in a lot of package (nscd, davfs, ...). I don't know if directory under /var/run should be erased on each reboot (FHS is clear about files but not directory).
But usually debian maintainers agree to do the modification. -- bacula can't start due to missing /var/run/bacula https://launchpad.net/malone/bugs/28921 -- universe-bugs mailing list universe-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/universe-bugs
