This points out a short-fall in the /var/run scheme: it can only be used
by processes running with an euid of 0 at the time they create the file.
If we have a /var/run/sendmail directory owned by the smmsp user then
sendmail can create its pid files there. Likewise for bind. The purgedir
function in /etc/rc (used to clean /var/run) will preserve the existing
directory structure under /var/run, so the sub-directory tree will
survive reboots.
