/dev/null permissions spontaneously become crw-------

Every so often, once in a couple of weeks or so, /dev/null spontaneously becomes unreadable and unwriteable for group and others. This happens on my laptop, on VMs and on servers. Only on Archlinux installs. It doesn't happen often enough for me to track down the cause.

Has anyone else encountered this?

Could it be a udev issue?

Not a Sysadmin issue, moving to NC...

Are you using emacs with TRAMP per chance?

early_adopter · 2015-04-10 15:22:19

Yes!!!

Could that really be the culprit?

Yep, encountered it myself. Right now you can either symlink /bin/sh to /bin/zsh (NOT recommended), or use emacs-git from the AUR (fixed in 25.0.50).

Bizarre! Many thanks. That might very well have been the last place I would have thought to look.
