+Subject: Applied patch from Matthias Schiffer which allows bootlogd to read
+ from a wider range of consoles. The console name is already passed in from
+ the kernel command line using "console=". We no longer filter out names as
+ strictly but do now check to confirm the "console=" device points to a valid
+ TTY.
