Hi,

just a minute before I wanted to shutdown my Linux box...and...
shutdown: /run/initctl: No such file or directory

Today I did the following ubdates
Fri Mar 30 04:03:37 2018 <<< net-misc/dhcpcd-7.0.1
Fri Mar 30 04:03:41 2018 >>> net-misc/dhcpcd-7.0.2

Fri Mar 30 14:37:35 2018 >>> media-radio/gpredict-2.2.1

What may have killed /run/initctl ?

/run has currently this content:

The timestamps look very suspicious...

Any idea of what has happened to initctl?

$ ls -l /run/initctl
prw------- 1 root root 0 Mar 16 21:50 /run/initctl|

I.e. it is a named pipe, which you can use to tell init things, like
to shutdown.

# man init | grep -A2 SIGUSR
SIGUSR1
On receipt of this signals, init closes and re-opens its control
fifo, /dev/initctl. Useful for bootscripts when /dev is remounted.

So, try "kill -SIGUSR1 1" to make init recreate that pipe.

NOTE:
If you use something else than sysv-init, the above might not apply.

See bug 651990. https://bugs.gentoo.org/651990

Either upgrade to sysvinit-2.89-r1, or run the following command
before rebooting or changing runlevels.

ln -s /dev/initctl /run/initctl

Isn't "/run/initctl" a Debianism?!

2.89?! A new version after so many years!

Looking at the upstream changelog:

Added Robert Millan's Debian patch to use /run/initctl as the named pipe
for communicating. This works around a limitation on the kFreeBSD branch
which prevents us from using /dev/initctl for pipes.

Hi,

thanks for all the help.

An update this morning has fixed the problem...but good to know
the backgrounds and workarounds, if anything like that happens
again... ;)

Cheers!
