I use archlinux and removed some /usr/include/rpcscv headers and .x files by mistake and libnsl.so.
I know it is stupid, but I don't know how to find them and put them back.
These files are related to PAM so I cannot use su, sudo or pacman and cannot do anything in fact.
I guess I should boot on usb drive and do something, maybe a arch-chroot and force install this with pacman ?
Would following the procedure from this link work ?
But will it even be the good version of the lib ?
