Something I've been wondering is if it's possible to get systemd to start tailing a log file when a unit is brought up, and to send that data into the system journal.
For the sake of discussion, let's say this program logs to a plain text file, and not to stdout. If I had to give an example, a Minecraft server would work.
I know of
systemd-cat, but this is just a third party app like
logger that doesn't tie into the unit system.
