This might be a flag in bioctl to force looping until the password is
correct. This way, you can force correct pasword for /usr, /var or
other and keep the current behaviour for partition like
/home/user1/encypted
I only have the former so my /etc/rc contains:
if [ X"${bioctl_flags}" != X"NO" ]; then
trap '' EXIT TERM KILL
echo 'mounting softraid'; until bioctl
$bioctl_flags 2>/dev/null ; do done
trap - EXIT TERM KILL
fi
# Check parity on raid devices.
raidctl -P all
