One point I just noticed from the flurry of messages last week I couldn't
entirely digest:

Syslog as in sending log messages to the system?  I use that every day
in my backup scripts, which logwatch then displays to assure me that
my local to disk, local to tape, and offsite ones all ran.

nohup, I've read that systemd has done a number on it.  But isn't it
in theory useful for starting a batch process and exiting that shell?
