Notes
For security reasons, screendump uses linux devices "virtual console screen" and "virtual console screen with attributes" to give access for screendump.
Ensure these files exist, using
cd /dev for i in 0 1 2 3 ...; do
mknod vcs$i c 7 $i
mknod vcsa$i c 7 `expr 128 + $i`
done
(filling in the ellipses) and give the device files appropriate permissions, or run screendump as root.
