Due to a few recent boxen failures, I need to repair my mailer, which
has to be carried out by the old sneaker-net to move required packages
onto a cloned mailer. Hence my request in the subject.

The back story is I cloned my mailer running on spining rust to a nvme
just under a year ago as a backup/recovery method, but my cloning method
was insufficient for a smooth boot up and now I need to
repair it. The boot up is missing the bit that creates all those
'recent' systems like /proc /sys and others(?).

~20 years of just installing Debian/Devuan ontonewish hardware means
I've forgotten all that knowledge of patching systems to tweak a bit
more life out of them. Also, the nvme contains the only copy of the
knowledge of aliases and access files for sendmail.

Either my web-fu is also badly shot now, but the urls from search
engines are trash and if this is the "knowledge" that AI engines are
built on, all is explained.

TIA.
