[kwlug-disc] systemd timer VS crontab

[Khalid Baheyeldin]

I am still on cron, and don't see a reason to move to anything else.

I use this command to edit and activate cron jobs for my regular user:

crontab -e

And I use this if the command needs to run as root:

sudo crontab -e

I don't mess with anything in /etc/cron* directly, except when there is no
other way.
For example, some script that packages installed there for daily crons, and
I need to change something.
For example, an email address or so.

There are even cases when I use cron for something that should be done
another way, just because it is easy.
For example, sometimes USB devices are not fully initialized when rtl_433
is run, so I have this:

# After a reboot, wait for a while, then restart the RTL-SDR stuff
@reboot /usr/bin/sleep 240; systemctl restart rtl-433mhz

Works consistently, and is much easier than messing with systemd units when
there is no obvious way.
