Booting ISO file from SUSE Studio with GRUB2

The build service “SUSE Studio” can generate ISO files. The software “GRUB2” can also boot some ISO files directly.
Which settings would you like to recommend for such a combination so that a corresponding boot menu entry will work?

Hi
See How to boot a openSUSE DVD from hard disk with Grub2 - Forums Feedback - openSUSE Forums

Thanks for your link.

The examples refer to a specification like “set root=…” there. I would appreciate if I can use a dynamic setting by a command like “search -f --set --no-floppy $ISO”.
I am unsure on the way to activate ISO files when they are stored in partitions of other file systems besides the directory “/boot”. Which GRUB modules should be loaded for this purpose?

I am curious on further advices.

Hi
You would set the root to the partition they are on, eg if sda5 would
be (hd0,4). Not sure if a search would work, but can always try, so
your sort of wanting a list of iso images to pick from?

All modules that implement individual commands (and their dependencies) are autoloaded. GRUB attempts to autodetect filesystems by dynamically loading modules too. You may need to load manually partition support (part_msdos etc), storage support (LVM, MD etc) and encrypted containers (LUKS).

It is nice when such a constant specification will usually work.

Not sure if a search would work, but can always try,

I am looking for more control on the search space so that corresponding GRUB settings can eventually be a bit more robust.

so your sort of wanting a list of iso images to pick from?

Yes. - I like some choice there.

How should configuration challenges be clarified further for various popular ISO files?

  • Would you like to share any more information on the application status around advanced file systems?
  • How are your experiences for corresponding software evolution in GRUB2 modules?
