today after installation of updates (linux, glibc, gcc*,systemd,zsh,..) and rebooting computer (notebook1 and notebook2) I faced with a problem:
tmux wasn't able to run in tty;
rxvt or any other terminal emulator for X wasn't able to open a window.
In logs I saw "can't open pseudo-tty" (rxvt) or "Can't open a pseudo teletype" (konsole) (may be not exact words).
I don't know what cause this problem (on second notebook before glibc and gcc update all was fine) but I found that devpts was mounted with wrong options, mounting devpts with
resolve the problem: tmux runs in tty and rxvt in X (don't check konsole though).
P.S. The same options are used on installation media
P.P.S. I post this message for reference, may be someone else faced similar problem.
Posted that yesterday on the bugtracker, as Rémy Oudompheng wrote, with systemd it's enough to just kill the devpts line in fstab altogether.
Thanks, I'll try today on my second notebook.
Edit: for the record: removing line with 'devpts' from /etc/fstab works like a charm.
