Thanks! I'll incorporate them as soon as possible, although a pull request
would work too. :)

While the scripts received their start in life from runit, they are now
meant to be framework-agnostic, supporting daemontools and s6 as well.
That is why I changed the name to supervision-scripts, although you could
make a virtual package "runit-scripts" that pulls supervision-scripts I
suppose.

I'm on runit 2.1.1-6.2 at the moment. Perhaps a change caused the issue?
Gerrit is probably lurking around the mailing list somewhere.

Indeed. To make things worse, I think/guess the reason Gerrit didn't make
the package install runit-init as default, is because of the sudden
transition without any scripts in place. Too many things depending on SysV
would break, including a working console to fix things (remember, there is
no inittab to spawn a getty), and now with the transition to systemd it
would be "all kinds of messy". I believe in Jessie (aka Debian 8) there is
a sysv-core(?) package that, along with systemd-shim, would continue to
make transitioning to runit easier by adhering to the old SysV method.
Nevermind that SysV is ignorant of /sbin/init and overwrites it when it
updates, killing runit-init in the process. After becoming tired of doing
"mv init init.sysv; ln -s runit.init init" many times, I now edit the linux
kernel parameters at startup with "init=/sbin/runit-init" and make sure I
use "init 6" to shut down, allowing both systems to be present.
Perhaps Gerrit could change the existing package to do the following:
+ Address the issue of /service vs. /etc/service via "ln -s /etc/service
/service", although this may be an issue with Debian's use of the FHS,
which I think forbids adding things in /, but I'm not sure. At least with
the symlink, removal of the package would remove just /service but keep
/etc/service intact, preserving your choices. This would help resolve some
of the instruction issues on the webpage.
+ Put in a "requires" sysv-core and systemd-shim for Jessie. Trying to
accomodate systemd while Jessie transitions would be too much trouble I
think; that could be addressed in Debian 9, when SysV is scheduled to go
away completely.
+ Allow /etc/runit to be created and populated. Hunting down the
installation files in /usr/share/doc/runit/debian isn't what I was
expecting. The instructions for installation are probably meant to be
fairly cross-platform, so you can understand what is involved (and
therefore, what you need to do to recover in an emergency). They can be
kept as-is with a simple addition, "If you are running Debian, the
/etc/runit directory has been created for you already, and you can go to
step blah-blah next. Otherwise, the following steps need to be taken..."
