* Add version 18-08-9-1
* Add variant to allow setting the sysconfdir: See below
About sysconfdir:
slurm has a server and a client.
To use the correct communication channel, the client needs
to be able to read the correct config. This config is in
PREFIX/etc.
Let's assume one has the server part installed as a system
package. This generally is a good idea, so that the server
gets started during boot. This means, that the config is
in /etc/slurm.
If one now wants to use the client part (library!) via
spack, one has a problem: spack's slurm looks in
SPACK-PACKAGE-PREFIX/etc for the config.
There needs to be a way to let the spack installed package
use the system's config.
So add a variant to override the path during build:
sysconfdir=/etc/slurm.
This is much like what happened in #15307 for munge.
