Portable to other systemd-using Linux distros.

sysv init scripts simply weren't portable between distros, leading to tons of non-standard, incompatible fragmentation.

Users simply couldn't simply take their own scripts over to another distro and expect them to just work, given said differences.

With systemd, unit files will simply just work between all systemd distros, given the standardized format.

Oh. That hasn't been my experience. Where did they standardize the names and set of the services you can depend on?

If the names of dependencies are the only unportable thing, we have indeed come a long way.

You're ignoring what the parent said and talking past.

It's not the 'sets' that are standardized, it's the set of commands that are applicable to a systemd service and to any systemd Linux distro that is.
