The problem here is that systemd does various useful things by itself that the other inits either don't do at all or push into (optional) other packages that helpfully come with init scripts so there is no dependency on that package on the part of the init systems. If these other packages then depend on other stuff, that other stuff will not show up in the init's list of dependencies.

Chances are that if you examine the transitive closure over all dependencies rather than just the direct dependencies of the init system, the difference between a system based on systemd and one based on SysV init with the same functionality will no longer be all that great.

And are the daemon init scripts included in the source-line count etc?

I thought one of the major selling points of systemd was that a 100-line systemd init script was *huge*. For sysvinit that's miniscule, isn't it?

So while systemd itself may be pretty large for an init system, that is far more than compensated for by the reduction in size in packages that make use of it.

Cheers,

Note that some of these dependencies are not used by systemd itself, only by some of its helpers.

Of more interest is the main memory which systemd-as-PID-1 actually uses. That boils down to 2.8MB on my system, vs. 0.8MB for sysvinit. Compared with its long list of features, that's not bad at all.
