Soo why does the /dev/changer device for this IBM TS3100 not show up?

What did I forget to install?

#NixOS #Linux #TapeLibrary #TS3100

Found the issue the documentation for #mtx is wrong.

The device is NOT called /dev/changer* it's /dev/sch*.

And btw the kernel module for it is "ch" but it was already loaded by udev.

#NixOS #TapeLibrary
