[TriLUG] Maintenance of a systemd machine

[Brian McCullough via TriLUG]

Folks,

I hope that everybody is having a FUN snow ( ?? ) day.  Here, SouthWest
of Raleigh in Apex, it was mostly ice with a dusting of snow on top, but
I hear that others had more of the white stuff.




In any case, I have a Debian SystemD machine where I need to run fsck on
various filesystems, such as /var and /usr.

Unfortunately, with a normally-running system, that is impossible, since
those filesystems, and others, are mounted and in use.

Even re-booting and choosing Recovery Mode gets me into a fully-mounted
running system.

Any suggestions for getting the system "almost" shut down so that I can
run fsck on critical systems?


Thanks,
Brian
