[Frugalware-devel] isohybrid images are ready for testing

[Miklos Vajna]

Hi,

Tonight I had some time to play with syslinux/isolinux and added support
for it in our mkiso tool. THe idea is that if we use that instead of
grub, then we can use isohybrid, which allows the same image to be used
as a cd image and as an usb installer.

Here is a test image:

http://ftp.frugalware.org/pub/frugalware/frugalware-current-iso/isohybrid/

Code:

http://git.frugalware.org/gitweb/gitweb.cgi?p=pacman-tools.git;a=commitdiff;h=c993cebe575da059ae320c5eabcab17fefdb4808

Motivations:

1) This way mkisorelease would take care of usb installers as well, and
the one doing a release would not have to copy it manually for each arch
to the -iso dir manually.

2) One less action that requires root privileges when building the
fwsetup package.

3) When we switched to initramfs we already got rid of one ugly "try to
guess the needed space, then copy to a loop device" step. This is the
same - with isohybrid we don't have to guess the size of the usb
installer, either (it will be exactly the needed size).

Please give it a good testing, and let me know if you find issues.

If there are no objections, I would like to have this by default in
1.6pre2 (but still having the grub part as a switch in mkiso, just in
case it's needed).

Thanks.

PS: I intentionally did not care about doing more than a minimal config,
but in case someone interested adding a splashscreen or something
similar, then I'm not against it. (You just need to hack syslinux.cfg +
png splash - and hey, this won't break virtual machines, unlike the grub
splash, that caused various kvm problems. ;) )
