@fabiscafe @okapi espechally in the form of an interactive desktop...
I could see it valid for multiple shell sessions, but #tmux & #screen cover that pretty well.
If one has to login into different machines then chances are #aithentification is centralized anyway.
Needless to say #modernizations like #SystemD don't happen because people like #Poettering are "hobbyless", but because the preexisting status-quo (#SysVinit) was slow, inflexible and error-prone by strict linearity and non-parallelization.
- With a literal
/etc/init
file one can literally get a system to hang due to a mistake (i.e. certain call doesn't get invoked correctly), whereas on #SystemD (and competing solutions like #LaunchD on #macOS and #SMF on #Solaris) your desktop / laptop will continue to noot even if it doesn't have a network connection.
Not to mention as Benno Rice explained: 'Shit just gotmore dynamic!': We don't have that one big ass maingrame and serial terminals, instead we have laptops that may he carried around a campus or traveled with all day and that constantly switch between wireless and wired networks and have VPN tunnels open and whatnot...
