Happens to all of us every now and then, I think.

Only if you can convince me to back off the bar you say I set too high.
I didn't set the bar. The people who say, "Compile it yourself if you
don't like it our way!" are they who set that bar. I'm not the one who
could have lowered that bar by putting systemd in a parallel

Well, LFS is not the only option, but it's the easiest of the options
I see for "compiling it myself" relative to the current discussion.
Everything else requires more experience, skill, and time.
Steve mentioned (off-list, was it?) that an OS without systemd is
(relatively speaking) not that hard to switch a new init under, where
an OS with systemd is significantly more difficult. Perhaps thinking
about that should point you in the direction I'm thinking.

As I say. this is not about your CV. It's about whether you understand
what "compile it yourself" means in this case.

Not as few as you think, I'd say, but the relative minority numbers
are really rather to the point that "compile it yourself" is not an
argument in favor of systemd. Quite the opposite.

Once again, I am not talking about anyone's CV.
And so you repeat a bunch of that self-styled cabal's talking points.
I let you waste my time that direction last night. I've got to get
some sleep tonight.
Build it yourself!
you say. Sure. Simple.
But cleaning out the bits and pieces of systemd api from various
packages takes time. Even if most of the packages have compile-time
switches, there is a lot of recompiling, and the current state of the
debian community does not allow for the community to do much testing
of the results. That means, really, that the DIYer has quite a bit of
regression tests to build, in addition to tweaking the build variables
and getting the compiles started on whatever passes as his or her
The partial replacement for su that started this thread is a case in
point. Every package that uses it will be rather intimately tied to
systemd, and I, if I were to build a completely systemd-free debian,
would have to re-write parts of those packages, hunt for or write
replacements for some packages, and write new regression testing for
In addition to the tweaking, re-writing, collecting alternative tools,
etc., it would mean for me, several days, minimum, of down time during
the build process, since my build environment is my workstation, and
my CPUs are not fast enough to allow me to compile and do certain
parts of my regular work at the same time.
Working from Debian sources is going to take more regression testing
than going through an LFS recipe. If I go the LFS route, using
binaries from debian or fedora would be inviting coredumps. Using
source, less so, but then I end up re-compiling more non-OS apps.
Even working from Debian sources, stripping out systemd means subtly
altering the APIs and ABIs, inviting subtle bugs. Subtle bugs tend to
be the most dangerous.
Going one's own way on something like this essentially means
abandoning the community. And because of the amount of work required,
you end up needing to start your own community. So compiling it
yourself in this case requires more than technical skill and a little
extra time. It requires a charismatic leader to start a new community,
"Build it yourself." is only a whitewashed version of "Don't let the
door hit you on your way out."
Be careful when you look at conspiracy.
Arm yourself with knowledge of yourself, as well:
