#83644 — Bug#1079399: linux: things written to tty vanish after a day or two

Package: src:linux
Version: 5.10.223-1
Severity: normal
X-Debbugs-Cc: tg@mirbsd.de

In /etc/rc.local I write a text file to /dev/tty11.
I have getty on 1-6 as usual and syslog on 12.

After booting the system, I can confirm this works.

A day or two later (I have not timed this exactly),
I can still Ctrl-Alt-F12 to read syslog, but trying
Ctrl-Alt-F11 does nothing, i.e. it does not even
switch from the syslog tty to the one with the text.
