I’ve been using emacs for 48 years since it was first invented by Richard Stallman at MIT in 1976 as a successor to TECO.
So I wasn’t too thrilled to not have it available to edit files on TrueNAS.
I just found a workaround: tramp mode.
So you from any linux you can install emacs on, you can do things like:
emacs /ssh:truenas:path/to/foo.txt
emacs /ssh:username@truenas:/path/to/foo.txt
