[Bug 2077225] Re: Ubuntu bootup is slow

[Julian Andres Klode]

apt-daily-upgrade.service has no Before= ordering constraints, hence it
can't hold up the boot; the blame analysis is pretty much irrelevant -
yes it starts at boot but that doesn't mean it needs to finish before
you can login.

The question I have then is why run-snapd-ns-chromium.mnt.mount only
starts at 2min 55.287s
