Well, on Gentoo I wrote the official docs on how it works, quite some
time ago...  :)  It is purely manual, so you can of course capture
whatever you want.  Just have it reboot to a shell and then save what
you need to.  An automated cross-distro core capture tool would
probably be useful.  I wonder if there is a generic one floating
around somewhere.
