It is very worthwhile having a clear division between Required and Important. A typical bootstrap should include Required but there is no need for any of the important packages and any which may be useful can be added explicitly. Please don't merge Important or lose the distinction between Required and Important - Required is sufficiently bloated already without adding Important. Far preferable (from an embedded perspective) to drop Important and make everything else into a default Priority (optional). IMHO There is nothing in Important that deserves bringing in everything else in Important. i.e. I'd welcome dropping Important, Optional and Extra completely and only having one default bag for everything not Priority: required or higher. > Do we > really care about the difference between required (insofar as required > means something outside of the essential set) and important, or between > optional and extra, for *any* package? Yes. The difference between required and everything else *is* important - the distinctions beyond that point are redundant. > The one remaining use case for priorities seems to be to be seed material > for installation scenarios.

This seems to > be what Priority: important is supposed to give you. I disagree, Priority: required is all that is necessary for that purpose. Important does not constitute a collected set of packages which all have the same usefulness. Nothing "important" is omitted by omitting Priority: important in a base installation. Even apt is not Priority: required and IMHO should not be so. > I'm probably on weaker ground in merging required and important, but I'd > like to know more background for why we have these levels and > distinctions. I'm away from my usual test installations right now but I am confident that Important is not as it seems. It is a loose collection of packages which, individually, are important to many situations but are not *required* by all. Installing one Important package does not warrant installing the rest. -- Neil Williams ============= http://www.data-freedom.org/ http://www.nosoftwarepatents.com/ http://www.linux.codehelp.co.uk/
