I've been running SpamAssassin for longer than seems realistic (2.28
with 1998 Red Hat Hurricane?). Anyway I have started moving
everything mail to yet a new machine, Ubunto LTS 24.04.01. That only
supports SA 4.0.0. I've been contemplating the pain of sideloading
4.0.1 into the system. Then I noticed single user installs. That
seems like a good way to keep a stable 4.0.0 mail server running that
updates when Ubuntu gets around to it and a work 4.0.1 for Loren
writing his rules.
Is such an attempt likely to blow up in my aged face or is it likely
to work like it I intend?
What is an Ubuntu "single user install"? Is this like a container or snap?
For other custom services (like WordPress or NodeRED), I'll create a
user just for that to sandbox it away from the rest of the system. I try
to do that on my Raspberry Pi projects, but it can be difficult if the
service authors didn't write for a mortal user. I've yet to deploy
PiHole because it seems to insist on having root to install. (Presumably
because it needs a privileged port for DNS, but there are ways around that.)
