OK, so I have my own 2-cents worth and experience with systemd...
In a nutshell, I do NOT like it. I have found CentOS 7 to have stability
issues that are TOTALLY UNACCEPTABLE for a SERVER. (might be fine for a
desktop, but NOT a server!)
And therein lies the rub -- systemd is designed from the get-go to
improve the "Desktop Experience" for Linux. Start faster, provide
feedback faster, do more crap automated, and automatically "filter" logs
and messages.
All GREAT things for the NOOB running Linux for the first time on a
desktop so they can run some app...
But most of the RATIONALE for systemd is an anathema to running a server!
In my own world, I have a CentOS 7 system running next to a CentOS 6
system. The COS7 system routinely breaks its network configs requiring
me to re-run the firewall startup (otherwise, my virtual machines
networking breaks at LEAST once a week!
On top of that, I usually leave a "console" (not :0) running with a
firewalled (e.g.: limited access by IP address) VNC connection -- and
this too BORKS at least once a week (when this fails, I have to ssh into
the box, stop the vncserver, remove the .X11 folder in /tmp, and restart
vnc. Not a HUGE chore, but given that I leave that very specific
interface up so that I can access VMs VERY QUICKLY in an emergency, it
sucks that often I have to do just that when something is going on --
and the delay is frustrating.
So what have I done about it?
Personally, I'm sticking with CentOS 6 for servers. Period. I've tried
and tried with COS7, and it just isn't right for a server.
I have to think there will wind up being some "splits" in some
distributions -- separating out server & desktop versions.
Just my thoughts... me, the guy who had QMT running on COS6 for more
than a YEAR before we (the QMT team) officially supported it... yeah,
that guy... is DONE with COS7!
We'll have to wait and see what the next rollouts are like from the
distros -- but for now, COS7 is NOT VIABLE as a server in my opinion.

Eric,
No problems as I will not use it.
It seems CentOS6 does not have systemd.
I dislike the idea of aggregating everything into
1 process.
We have a VM of CentOS6.7 now and are working
on migrating everything this weekend.
CentOS6 is supported until 2020 I believe so this might
see me out of computing and in my grave. If not then it
at least buys me time to learn a different os that does
not have Systemd.

Hi,
Just because "everyone is going that way" does not make it right.
I can quote "If it ain't broke don't fix it!".
There are many distros not migrating to systemd and those that are
seem to me to have a core user group that are spawning or forking a
separate distro that does not use systemd.

This may give you some insight. It is a good place to start making your
mind up on the pros and cons of systems.
I chose Debian (Devuan) as there is a site
http://qmailrocks.thibs.com where
there are instructions on Debian. Essentially this is an up to date
version of
the old QmailRocks site that died a slow and painful death.
I am happy to converse with anyone but maybe we should do it off
list as
it is potentially not constructive for QMTers.
I will have a VM up and running over the weekend for testing.
NB I am not intending to start a big heated discussion I simply
wanted to
know if anyone had already changed.

Yeah - I too dislike the new system stuff. but everything is going
that way it seems. You could Gentoo and build it how you like, but
that is its own set of issues.

systemd, kthread and all the other rubbish you dont need on a server.
However just found out that Debian as systemd now as well.
So the point is moot.

Hi folks,
I am sick of CentOS and was hoping someone had been using QMT on
Debian.
If anyone has done this I would love to hear your experiences.
TIA.
