-grml isofrom=/dev/sda1/grml.iso Use specified ISO image for booting
- Useful when booting as a rescue system from harddisk - just boot
- the according grml kernel and initrd using the bootoptions
- "boot=live isofrom=/dev/sda1/grml.iso"
+grml isofrom=[fs:][/device]/grml.iso Use specified ISO image for booting.
+ Useful when booting as a rescue system from a different device.
+ If you want to load the image from a device different from the root device
+ specified through the bootloader, prefix its device path to the path, like
+ in "/dev/sda1/grml.iso".
+ Internally, the initrd will mount the given device, automatically detecting
+ the file system.
+ If needed, prefix the file system separated with a colon character to
+ override the automatic detection, like in "reiserfs:/dev/sda1/grml.iso".
+ As an example, boot the according grml kernel and initrd using the
+ bootoptions "boot=live isofrom=btrfs:/dev/vda40/path/to/grml.iso"
