If you have a password protected image (a password required to boot, not
just restricted) then lilo -R imagename will prompt at boot time for the
image password, then time out and boot the default image. This makes it
impossible to boot into a password protected image unless you're at the
Here's a sample of what I use (sorry for the line wrapping)
Without the "password" line I can initiate a remote upgrade with
lilo -R reinstall; reboot
but of course I have to password protect this image.
This is unfortunately a limitation of the way that password mode works in lilo.
You can remove the timeout section from your lilo.conf and you won't have to
worry about it timing out in the future, although then it won't ever boot into
the default without human intervention.
