Inheriting TERM variable leads to broken terminal

[mpickering]

nixos-shell will inherit the TERM variable from the user environment which leads to a broken terminal in some situations.

For example, I have TERM=rxvt-unicode-256color, which is inherited and leads to a broken terminal. Probably because rxvt_unicode is not in the system packages?

Does inheriting $TERMINFO_DIRS fix this issue?

[mpickering]

No, it's still broken inheriting that variable.

I have:

echo $TERMINFO_DIRS
/home/joerg/.nix-profile/share/terminfo

I assume it has your system profile in there? So maybe something like TERMINFO_DIRS=$(realpath $TERMINFO_DIRS) could fix it.

One would need to add all terminals to environment.systemPackages to fix this properly.
