Hi Frank

Another (imho simpler and safer) approach would be to change the group
of /dev/vcsa f.e. to "vcsa" (if this group does not exist yet you can
create it) and give the group read access to these files. If you add
yourself (or the user running /usr/lib/mc/cons.saver) to the group vcsa
you will have the rights to read the /dev/vcsa devices without needing
to set SUID or SGID bits.
