..it is very nice to learn I can read e.g. postgresql database files
while boycotting e.g. postgresql, using strings and all sorts of fancy
tricks to e.g. verify some postgresql developer's statement on systemd
people playing nice or not.
..it would also be very nice to learn of a way to decode and read binary
systemd journal logs without having to run systemd or without having
to hire expensive expert witnesses to decode and read my own binary
systemd journal logs from my final days on Debian Jessie.
..one very nice way of learning of a way to decode and read binary
systemd journal logs without having to run systemd, is listening
to wise answers from those who knows the correct truth about how
to decode and read our own binary systemd journal log files. ;o)
..so, how about answering my question?
Preferably correctly, if at all possible.
If not, pointers to hearsay is useful to help try discover
the (ugly?) truth.
All I've seen this far, is confusion, deflection, trolling
and diversion away from the context and my question.
..to reiterate: Is there a way to decode and read those binary
systemd journal logs on classic POSIX/Unix etc forensic systems
_not_ running systemd?
..e.g. using my namesake's example postgresql to translate the binary
files into some human-readable format?
..the "strings" approach suggested by John Hughes requires an intimate
knowledge of systemd and might be relevant if the investigations were
on "systemd sabotaging Devuan playing _new_ zero-day dirty tricks."
..so, the systemd crowd should have an interest in e.g. exposing
"Devuan incompetence and paranoia" by coming up with an easy way
to decode and read binary systemd journal logs without having to
run systemd, to prove their case on "Devuan incompetence and
paranoia on systemd", rather than confirm my current belief.
