[Fedora-livecd-list] Trimming the size of LiveCD's

[Jon Steer]

I'd be interested in the "-" lines that you use to strip the files out.

As the generator of a console-based server distribution I am
interested in losing as many extraneous packages as possible.

For me, stripping down the size of the ISO has more to do with space
considerations for either USB-based distributions or when I'm booting
the LiveCD into a VM and I'd like to save real memory space.
