About bad commandline/broken/obsolete bootloaders: I was thinking you could use a first kernel booting an initramfs with kexecboot, then the commandline for the kexec'ed kernel could be read from a file (or mangled in the code as done for Zaurus). BTW it seems the issue is very old, as mentioned in the old bootmenu-images in oe-classic http://cgit.openembedded.org/openembedded/tree/recipes/initrdscripts/files/01-bootldr-buster.sh?h=org.openembedded.dev Cheers Andrea _______________________________________________ Angstrom-distro-users mailing list Angstrom-distro-users@linuxtogo.org http://lists.linuxtogo.org/cgi-bin/mailman/listinfo/angstrom-distro-users
