Failure - tmux on today's -current

[ci4ic4 <ci4ic4%proton.me@localhost>]

Hi,

Have I missed something? I could not see anything in UPDATING regarding changes around tmux. It stopped working on my today's amd64 system - I am about to test it on an aarch64 one in a moment. I started a session overnight - running pkg_rolling-replace - and tried to attach to it in the morning and am getting:

$ tmux ls
0: 3 windows (created Thu Mar 26 00:41:33 2026)
$ tmux at
open terminal failed: not a terminal

It works if I start tmux session as root. Just in case, I also recreated the device tree to no avail.
