Just curious Sven. Why was this not supplied as a manpage or something, 
as far back as wheezy?

I could fix the perms on /var, and restart everything that failed, and it 
would be fine until the next reboot, which reset the perms so /var was 
only writable as root. Didn't anyone think of the stuff that runs as a 
user? Fetchmail/procmail/nut and heyu are all killed by that, so I 
edited the configs to put their logfiles in ~/me/log. Works a treat 
after also fixing logrotate to access them there. My thoughts on the 
geniuses that decreed that aren't generally printable.
