By linear extrapolation, about 7 minutes per terabyte on an EPYC 7402, which can handle up to 4 TB.

Attempts to justify new init software by "it boots much faster" fall flat.

OSEs aren’t limited to running on physical hardware, fast startup for VMs is still beneficial.

Of all my Linux VMs, Alpine Linux boots the fastest--practically instantaneously. Alpine Linux doesn't use systemd.

Parallel init only helps on large, multi-service systems, but those are precisely the ones that (1) rarely reboot and (2) will have relatively long boot sequences, regardless.
