spamd and the nobody home

[Bob Proulx]

While looking at the startup errors I noticed that spamd starts and
logs these errors.

    Jul 18 20:29:51 debbugs spamd[16649]: spamd: using default config for 
nobody: /var/lib/spamassassin/nobody/user_prefs
    Jul 18 20:29:51 debbugs spamd[16649]: bayes: cannot open bayes databases 
/var/lib/spamassassin/nobody/bayes_* R/O: tie failed: Permission denied

I look and find a very old set of files there that do not have
permissions due to spamd being explicitly run as -u nobody but the
files set up to expect them run as debian-spamd.

  /var/lib/spamassassin/nobody:
  -rw-r--r--  1 debian-spamd debian-spamd 171749376 Jan  6  2012 auto-whitelist
  -rw-------  1 debian-spamd debian-spamd        22 Jun  8  2012 
bayes.lock.debbugs.gnu.org.20036
  -rw-------  1 debian-spamd debian-spamd        22 Jun  8  2012 
bayes.lock.debbugs.gnu.org.20099
  -rw-------  1 debian-spamd debian-spamd       105 Jun  8  2012 
bayes.lock.debbugs.gnu.org.9375
  -rw-------  1 debian-spamd debian-spamd     52944 Jun  8  2013 bayes_journal
  -rw-------  1 debian-spamd debian-spamd 170110976 Jun  8  2013 bayes_seen
  -rw-------  1 debian-spamd debian-spamd   5234688 Jun  8  2013 bayes_toks

I decided to fix this.  But don't want to use those files from 2012
and 2013 so I move the directory to old-nobody and set up new files.
I will experiment around to see if I can make this usable so that
there can be Bayes learning for it.
