I attached a variant of 60_grub-imageboot with the following changes * Make stripping filename extentions more robust. * Improve quoting. * Refactor.
This is based on the packages git head with additionally http://grml.org/patches/0001-Probe-device-where-image-is-being-stored-using-grub_.patch applied. * Carsten Hey [2011-06-24 11:49 +0200]: > Two ways to make grub-imageboot more configurable that come to my mind > are: > * read options for ${imagefile} from ${imagefile}.config if it exists > * let the users add additional file name extensions with custom options > in /etc/default/grub-imageboot, e.g., .raw-hdd, which uses "raw" and > "harddisk" as options * a new config file with the following syntax (lines starting with # could be ignored): [FILENAME] [OPTION] ...
