Bug#132542: sysvinit=2.93-5 (Was: please make /etc/init.d/rcS a conffile)

[Dmitry Bogatov]

I uploaded sysvinit=2.93-4, and sysvinit=2.93-5 just after, since I
forgot credit to Thorsten. Changes are mostly cosmetic, except following
changes:

  * Check for presence of backlight-related virtual files in `brightness'
    initscript (Closes: #918966)

Incorporated improvemens to `brightness' script, provided by Thorsten Glaser.
Many thanks.

  * Make /run/shm symlink to /dev/shm, not other way around (Closes: #851427)
    + Thanks: Dolphin Oracle <dolphinoracle at gmail.com>

Reportedly, previous state of affairs broke some flatpacks. I expect
most users to not notice this change.

  * Move {rc, rcS} scripts from /usr/libexec to /lib for convenience of
    non-users of initramfs.

After hot discussion, I have to admit -- I was wrong. Sorry. Sysvinit
will not drop any supported configurations.

I intend sysvinit=2.93-5 to be last upload into unstable before Buster;
all other changes are to go to experimental.

I welcome everybody to join the cause. bin:initscript could use more
hands and expertise, expecially NFS-related. Also, if someone is capable
to configure IRC notifier on salsa it would be great.
