Bug#916749: systemd-cron: Tries to launch unreachable commands

[Alexandre Detiste]

control: reassign -1 dma

Hi,

This looks more like normal behaviour.

tchet at brix ~ $ [ -x /usr/sbin/dma ] && /usr/sbin/dma -q1
tchet at brix ~ $ echo $?
1

The crontab should maybe have been written this way, to always return "true".

[ -x /usr/sbin/dma ] && /usr/sbin/dma -q1 || true


I'm assigningg the bug to "dma".
dma maintainers can close it if they feel so.

Greetings,

Dear Maintainer,

I just switched from cron to systemd cron. I now have every 5 mintes
following email :

/usr/sbin/dma does not exist, thus the action should not be executed.
