Primaries are essential for cross-building so that the apt-cache can get accurate data for whatever architecture is required. It's quite specific to emdebian, it doesn't help that much in a general script like piuparts of pbuilder - except that I would prefer that a primary is always available because it makes cross-building so much easier. > > debootstrap: > > uses ftp.debian.org as default mirror. > > If ftp.debian.org doesn't contain all architectures, then that's a bad > default, imho.

That would be very handy! The default could then be the closest/quickest primary mirror. It would be important (from my perspective) that this default is required to be a primary mirror - maybe offer the user only the list of primaries and don't allow manual editing. (The current list of primaries is in the emdebian-tools postinst or here: http://www.debian.org/mirrors/list ) -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
