Nothing makes my life easier than cleaning out crontabs of things that wake my box in the night and find out that something still gets launched. Oh yes, systemd now has timers no one asked for.
Nothing makes my life easier than disabling a service then masking a service then masking it's sockets, then blanking files then chattr +x those files and end up having broken ubuntu instance because there are so many ways to launch a service it's not even funny at this point.
Nothing makes my life easier than finding out multi gigabytes /var/log/journald folder that has exactly zero reasons to exist because text-based logs are still collected and properly rotated in a place where any sane person would expect them to be.
Shall I continue or do you get the gist? :-)
