Hmm, I thought one of the prior posts said that .fetchmailrc needed a
special context (it's certainly different from the home user's other
contexts).  A further problem was that running fetchmail created a
.fetchmail.pid lock file that apparently needed special context, too.

$ ll -Z .fetchmail*
-rw-------. tim tim unconfined_u:object_r:user_home_t:s0 .fetchmail.pid
-rw-------. tim tim unconfined_u:object_r:fetchmail_home_t:s0 .fetchmailrc

This (above) worked when called by root in the command line, the user
in the command line, or crontab, but not from rc.local.

Inheriting *my* home directory context wouldn't get it working in the
case I was trying (from rc.local):

$ ll -Zd /home/tim
drwx------. tim tim unconfined_u:object_r:user_home_dir_t:s0 /home/tim

Since I was launching fetchmail with "su" in front of it, it ought to
be running as me.  Which, normally, wouldn't have suffered all the
problems I was having with it.

I even tried changing the command further, to use my environment:

su --login tim -c "/usr/bin/fetchmail -d 900"

Which also fails, but with even less useful information in the logs
(zero mention of fetchmail).

I even tried making a /etc/fetchmail script, containing my commands,
and launching that script from rc.local, instead.  Still didn't do me
any good.
