The last is exactly what hardly anybody will object.
I must confess all my jails are still on FreeBSD 9.3, configuration is in
/etc/rc.conf (jails set up without using special tools or scripts, just by
following FreeBSD excellent handbook - "by the book" ;-) I just took a
quick look into man jail.conf. All still is plain ASCII text; different
syntax, but it doesn't call for any complaint in me. What I described
(systemd has many controversy sides, I mentioned only format of config
file) is different: imagine rc.conf or jail.conf all wrapped into XML tags
inside, which is pure junk obscuring everything, and serving mere purpose
of GUI tool nicely presenting that information. THAT is a mess! jail.conf,
though different in syntax from what I have in /etc/rc.conf, is still OK
for me. I just got scared by someone saying what sounded to me like: I
want GUI config tool, I don't want to edit with vi (or any plain text
editor) plain text config file. Next step will be config file is not human
readable. Which scared me to death, so I decided to speak up.
