This PR:
https://invent.kde.org/plasma/plasma-login-manager/-/merge_requests/130 seems
to have prolonged my boot up time.
Now /usr/lib/systemd/system/plasmalogin.service
has a line
ExecStartPre=-udevadm settle --timeout=10
systemd-analyze critical-chain gives:
graphical.target @14.414s

When I comment it out, systemd-analyze critical-chain gives :

└─proc-sys-fs-binfmt_misc.automount @911ms
I understand this is neede on some hardware, but do we need this for the most
of us who have a hardware that does not need that?
