Yes. When I built the machine in, I think, 2018, I gave it a small
(by today's standards) SSD as a boot drive, along with a much bigger
HDD. I setup some partitions on it to try to manage the limited
space. I wouldn't do it again, but what's done is done.

Sorry, that was an error. I meant `apt autoremove`. It's documented in
the apt manpage.
