Hi,

we unlikely could explain much more than the Wiki does, without becoming
off-topic for this mailing list, so just read
https://en.wikipedia.org/wiki/Systemd.

I don't know if the "Category:Linux distributions without systemd"
provides correct information.

"This document compares Upstart and systemd with a view to aiding in
the transition to the latter":

https://wiki.ubuntu.com/SystemdForUpstartUsers

The Arch Wiki provides a few hints related to systemd, that also apply
when using Ubuntu flavours, e.g. using the 'strings' command:

"While the journal is stored in a binary format, the content of stored
messages is not modified. This means it is viewable with strings, for
example for recovery in an environment which does not have systemd
installed. Example command:

$ strings /mnt/arch/var/log/journal/af4967d77fba44c6b093d0e9862f6ddd/system.journal | grep -i message
" - https://wiki.archlinux.org/index.php/systemd

Upstream:

https://www.freedesktop.org/wiki/Software/systemd/

Note, Ubuntu fully migrated to systemd, any discussion about pros and
cons on this mailing list could easily lead to moderation, since such a
discussion unlikely could stay reasonable for this list. IOW this list
not necessarily is the wrong place, but most likely is the wrong place
for continuing this thread.

Ralf
