I just learned about the awesome "lilo -R" command. The
man page says:
-R command line
This option sets the default command for the boot loader the next
time it executes. The boot loader will then erase this line: this is
a once-only command. It is typically used in reboot scripts, just
before calling ___shutdown -r___.
This allows you to test new kernels on remote servers, and it will
revert back to the lilo.conf default during the next boot. A regular
reboot, remote power cycle, or passing 'panic=10' kernel option which
reboots upon panic would fallback to the previous default.
Does GRUB have anything similar to lilo's -R? This is a totally useful
function and I would really like to avoid using lilo.
If this functionality is truly missing from GRUB then this is another
project for me.
Hi Warren,
Yes grub has the "--once" option to savedefault:
savedefault --default=N --once
used in the grub shell.
