[Nix-dev] Modifying the init system (introducing S6 supervisionsuite)

S6 has logging without the unfixable bugs of JournalD

S6 doesn't insist on breaking xinit/startx-like functionality.

S6 doesn't barf if you put your swap into fstab.

SystemD has its unique WONTFIX bugs that no other init system shares
(sometimes not even UseLessD, although it is a minimalistic fork of
SystemD).

For me these bugs are showstoppers. I recently had a task at work that
was _much_ simpler by running 3 identical X servers.

Well, nix-rehash is something many people need anyway, so SAL will be
done in some way (hopefully shared with NixOS).

The hard part is apparently finding out the exact list of requirements
for SAL after which people won't object to SAL use in NixOS.

Minimal init-less system boot is actually _not_ a lot of work, and 
porting services is currently prepared for the reasons of user services…
