Re: Who cares about start up times?
Either way, the difference between 20 or 30 seconds to boot is irrelevant - even a minute or two would not be 'too long' - and the price of systemd to shave those seconds off is too high.
This doesn't just apply to desktops, where that timeframe could be important to users. It also applies to physical servers, which really have never booted fast in my experience with the SAN or SCSI wait times to scan volumes, wait for FLOGI/PLOGI, etc. Just last weekend, a system maintenance had a 15 minute window just for the shutdown and reboot of an ESXi host, and that's without starting any of the guests.
Start up times have accelerated to the point where developers should definitely spend their time solving problems that actually matter, like figuring out how to clean this systemd virus from new Linux distros.
