suse 8.0 login manager reboot

tkmbe · 11-24-2005, 07:10 AM

Hello

In suse 8.0 there was the ability to reboot into an other system from the graphical
login manager. It seems that there was generated on the fly a boot.ini which then
was booted.
With this feature it is possible to boot an other kernel that the default one
in an embedded system wihout console support.

Does anybody know which package/software was used to do this and
if this was a suse specific feature or a kde loginmanager feature?

Thanks for any hints

It's a kdm feature and is activated through kdmrc:

Code:

[Shutdown]
# The command (subject to word splitting) to run to halt the system.
# Default is "/sbin/halt"
HaltCmd=/sbin/halt
RebootCmd=/sbin/reboot
# The boot manager KDM should use for offering boot options in the
# shutdown dialog.
# "None" - no boot manager
# "Grub" - Grub boot manager
# "Lilo" - Lilo boot manager (Linux on i386 & x86-64 only)
# Default is None
BootManager=Grub

But it's actually a grub command, changing the default temporarily to another setting:

Code:

grub> savedefault --default=3 --once

Thanks abisko00

I use lilo not grub. How is this done there? Also with grub commands? Is lilo.conf converted temp. to grub conf ?
I use now suse 9.3 and this feature has gone ...

Thanks for more info!!

Sorry, I can't help with lilo. I found the grub command only by accident in one of the log files (probably /var/log/kdm.log). I also never used 9.3 (jumped from 9.1 to 10.0), but I think the feature is simply not activated in kdmrc (BootManager=none). The grub command will only work when you are using grub.

I suggest you set in kdmrc 'BootManager=lilo' and restart KDE. Then try if the feature is available and have a look in kdm.log for the command. This is how I have done it.

Ok will try it.
If I figured out how to use with lilo I will post it here.

Thanks a lot for the info!

After try and error with kdm config files and suse 9.3 config files
I were able to have the same behaviour like in 8.0.
The problem was the default of Grub in file /opt/kde3/share/config/SuSE/default/kdmrc
After changing to BootManager=Lilo
and removing file /etc/opt/kde3/share/config/kdm/kdmrc
and the command SuSEconfig --module kdm3
it worked!

Now the clue eith lilo:
To reboot temp. other image you can do

lilo -R <ImageName>

I really don't know because I have not seen this in the manpage first ...

Thanks again and greetings
