"Starting anaconda", "Enable Kdump", on anything RedHat.

Unexpectedly, the 'bootable thumb drive' models are actually pretty great — not the installers, but the ones that boot straight into a GUI that works and is usable. I haven't used one as my personal Linux uses predated thumb drives, but I have always (mistakenly?) assumed that once you're booted into a liveCD, you can click 'Install on a drive partition' and it will actually do something coherent and GUI and reasonable. Have I been too optimistic? Probably, yeah :(
