Udev rules to automatically call rfkill unblock wifi when new network
devices are added. Some drivers seem to default to blocked state which
is really not wanted.
Some wifi drivers create eth* interfaces, so call rfkill unblock also
for those.
Get back the /etc/rc.local rfkill call for now.
Fix /etc/profile so that the lines added by smartboard packages do
not break scripts using sh (like x2go).
The "smart" scripts run from /etc/profile are written in bash, so
we should not even check for their existence if the shell is not
bash.
