base-files: resize only serial tty's in profile
[Backported from master.]
We don't want to run resize on non serial consoles. There's
been an earlier attempt (
6557787), so this builds upon that.
The problem we're seeing is that if there is text buffered in
the virtual console (like from a desperate user trying to
enter login details), resize will get stuck while calling
ioctl(tty, TCSETAW);
Since serial consoles are named (not just numbered), this
change limits resize's reach even further to run only on
/dev/tty[A-z] (thus avoiding /dev/tty[0-9]).
