A quick one... I noticed this folder in
/ on Kubuntu 15.10:
drwxrwxr-x 2 root root 4.0K Dec 12 02:33 cdrom
Why is it there and how is it used? Shouldn't CD-ROMs be (auto-)mounted in
/media by udisks2 (or manually wherever I want them)? My current system doesn't have an optical drive, so I can't test this for myself. I just came across it while identifying folders in
/ to exclude in my rsync script.
