Solved: 24.04 ssh down with missing directory error

This article 
<https://discourse.ubuntu.com/t/sshd-now-uses-socket-based-activation-ubuntu-22-10-and-later/30189> explains 
the change. What I don't understand on my system is why has it worked 
for so long, then failed? The article plainly states that ssh has 
changed from a resident service to an activated socket instantiation 
mode to reduce memory requirements when not in use, but that change was 
implemented in late 2022, and my system was a fresh install of 24.04 
last summer. The system had not been rebooted in at least a month, so my 
question is how did this break my previously running implementation?


Another article 
<https://forum.openmediavault.org/index.php?thread/51087-missing-privilege-separation-directory-run-sshd/> 
goes into great detail for how this works under Debian, so I figured 
it's got to be pretty close to what went on with my own system. Am I on 
the right track here?
