Hi!
I just tried to put these ISOs on the same USB stick:
grml64_2011.12.iso grml32_2011.12.iso grml64_2011.05.iso grml_2011.05.iso
(I wanted to have the older versions around because my paranoia tells me I will need one of the programs that were deleted, by I want to use the newer versions to find out if I really do.)
It turns out that grml2usb used the flavour to generate the syslinux menu entries:
Debug: 2012-01-05 12:31:35,505 Note: you can boot flavour grml using 'grml' on the commandline. Debug: 2012-01-05 12:31:35,505 Note: you can boot flavour grml32 using 'grml32' on the commandline. Debug: 2012-01-05 12:31:35,505 Note: you can boot flavour grml64 using 'grml64' on the commandline.
So I'm able to boot the older versions because I specified the later on the command line, and grml32_2011.12.iso because the flavour changed to grml32.
And grml64 was selected as the default flavour because it came first. Only the version was replaced.
Looks like I would have to fiddle with the contents of one of the grml64 ISOs to accomplish my goal. Any suggestions? Yeah, I know, buy another USB stick, they're cheap ;-)
Thanks, Luep Christoph
