I’ve installed Void Linux base image and my backspace key is broken when I am root, it types ‘^H’ instead of erasing. Function keys also type something weird, but at least the brighness-related ones do work.
This only applies to the root shell, it all works perfectly when I login as a normal user. Probably a bashrc issue?
UPD: I typed ‘stty erase ^H’ in the shell and it now works.
I noticed this as well on Void, but never really looked into the cause, but like other people pointed out, the root user must be lacking some shell-related configuration or something. For me tab-completion and up arrowing through the command history was also broken for root. It frustrated me, but never enough to bother trying to solve it lol.
