Rotation without losing writes

The rule for app.log has never run yet. Check it before the first run: after rotation the program must keep writing.

Exercise · do it

Rotate the log without breaking writes

You are in /srv/rotate-lab. Rotate the log by the logrotate.conf rule with the /srv/rotate-lab/state state file. Afterwards the old log text must sit in app.log.1, and the /usr/local/libexec/lab-log-write program run as you must append to the new app.log. Later rotations by this rule must keep the log writable for it too.
