Raspbian init script bug

[gdt]

Hi folks, Not sure which bugtracker to log this against, so I'll simply record it here for reference by others.

The file /etc/init.d/mathkernel doesn't contain a LSB header and this causes issues when adding or removing other daemons using update-rc.d (usually called by as part of the installation or removal of the a daemon's package).

Solve this by adding a header. Specifically, add this to the start of /etc/init.d/mathkernel

Code: Select all

#!/bin/sh
#
# start/stop mathematica daemon.

### BEGIN INIT INFO
# Provides:          mathematica
# Required-Start:    $network $local_fs
# Required-Stop:     $network $local_fs
# Default-Start:     S 2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: Mathematica remote services
# Description:       Allows remote use of Mathematica.
### END INIT INFO

What issues? I just see a harmless warning.

Well, that's embarrassing. That should be fixed in the next update. Thanks for bringing it to our attention...

It's harmless as long as you don't have packages which cause a unresolvable loop. For example, attempt to install both mathkernel and watchdog. One of the two services won't start.

Has this init.d script been removed from newer installations? I just re-installed wolfram-engine and there is nothing related in /etc/init.d

OT: desktop shortcuts still not automatically generated. Works from the menu shortcuts, though. Edit: ah sorry, maybe creating desktop shortcuts is not part of the installation anyway. If you want, a desktop icon is easily added by right-clicking the Mathematica icon in the Education menu and selecting "Add to desktop." Never mind this off-topic paragraph!

Yes. That particular script was not supposed to be present in the first place. There should be a much more robust solution for using a daemonized kernel in the near future.
