Help! Crontab change does not survive reboot, despite following guideline

[bert.r]

Hello everyone,

I'm having a TS-253A (now running QTS 4.4.2.1310) on which I'm having a problem with one line in the crontab. Two years ago, when I set up the system, I added a couple of crontab lines. They all survive reboots except for one. Very likely, I've added the surviving lines in a different way than the disappearing one, but I don't remember that anymore.

The disappearing line is this:

Code: Select all

0 21 * * * /opt/sbin/logrotate /opt/etc/logrotate.conf

I add that as described here:

Code: Select all

vim /etc/config/crontab
crontab /etc/config/crontab && /etc/init.d/crond.sh restart

Still, when I reboot, it's gone. In the past two years, I've been applying QTS updates regularly and faced this issue with every QTS version.

Any idea?

Regards,
Bert

Any idea?

The cron system in QTS periodically re-writes the crontab. Which has a bad habit of removing user customisations.

If you want to stick with QTS cron, you'll need to keep re-adding your crontab entries.

Too bad!
What would be the alternative for the QTS cron?

There's also cron available via the Entware QPKG.

Or you could dump QTS entirely and load your own OS. Debian is a popular choice.

Thanks a lot!
