Subject: Loose dependencies so we can be installed on squeeze
X-Git-Tag: v0.16.1~30
X-Git-Url: https://git.grml.org/?p=grml-live.git;a=commitdiff_plain;h=7a0c07b715261193f94454202248f62bdbd857b8;ds=sidebyside

Loose dependencies so we can be installed on squeeze

grub-pc-bin was part of grub-pc during squeeze, and ipxe didn't
even exist. Both are now in Recommends, and users of squeeze
are expected to install grml-live-compat.
