------------------------


1)
Newer versions of OpenSUSE mount remote filesystems based on the network interface.
Thus the init-script(s) need the following:

# Required-Start: $network $remote_fs
# Should-Start:   network-remotefs


2)
Should provide LSB-compliant return codes for program not installed (exit 5), program not configured (exit 6).
The availably of NFS mounts probable still needs to be checked.

3)
Stopping the execd via the init-script cannot rely on qmaster being available at that time.
As a backup, the configuration files can be used directly to obtain similar information.

4)
Recombining the init-script for master/exec would greatly ease allround maintenance.
This was already the case several years ago, but it got dropped rather than sorting out the logic.
I believe to have sorted out the logic.

[The LSB for init is at ​http://refspecs.freestandards.org/LSB_4.0.0/LSB-Core-generic/LSB-Core-generic/sysinit.html]

1) is now fixed.
4) doesn't look as if it would allow separate services, which is important,
at least for shared installations.

We also need at least restart as an action.
Check the Fedora and Debian versions.
