[SOLVED] problems after system update and running pacdiff
Today I updated the system, ran pacdiff to deal with pacnew files and got distracted while doing so. As result I overwrote the old /etc/group, /etc/passwd, /etc/sudoers and now my password is not recognized, I can't sudo, I can't login as root (and I'm afraid that if I turn off my computer I won't be able to log back in). What can I do to fix the problem without reinstalling the system?

Reboot to a LiveUSB?

Re: [SOLVED] problems after system update and running pacdiff
You could try to restore an old state, using the backup files kept in /etc:
group-
gshadow-
passwd-
shadow-

Re: [SOLVED] problems after system update and running pacdiff
Thank you everyone! I panicked a little bit the other day when my computer refused to recognize me but your advice helped 
I booted from LiveCD, did chroot and restored shadow, gshadow, passwd, group from the backup files.
