I should have read the man page before trying to use multiple commands at
once, but somehow it ended up causing a kernel panic?

Here's what I ran as root in tty0 (I think that's what it's called, it's
the thing I get to by pressing ctrl + alt + f1):

herd enable ntpd start ntpd

ntpd had been disabled because it kept immediately exiting, which it was
doing because I had another one running, which I had running because it was
originally disabled because it couldn't fix time errors of over 1000
seconds without the -g flag and so immediately exited every time and was
disabled by shepherd automatically. I don't know how relevant any of that
is.

Ouch!

Fixed in Shepherd commit 9161450cb800f09ba617f456df9d2ec55ebf242b.
I’d like to prepare a Shepherd release soon with this fix, sounds
worthy…

Thanks for your report!
