In an AppVM based on debian-11 template,
script fails to launch after this:
openat(AT_FDCWD, "/dev/ptmx", O_RDWR) = -1 ENODEV (No such device)
I find the thing puzzling, as a debian-10 AppVM has no such issue, despite
/dev/ptmx having same major/minor/perms. Any idea where such a difference could come from ?
Update: This also caused my running
screen to refuse creating more windows, and a VM restart made the problem go away. Could not find anything meaningful in the log to explain this event.
