pkgdetails already parses wget's output and passes progress information directly to the boot-floppies, so I don't see how also returning error messages is breaking new ground. > In any event, I think you'd be better off handling this within > boot-floppies.

It seems more robust for debootstrap to return a meaningful error message, rather than the boot-floppies having to guess why it failed. Matt
