Thanks. Looking at the list, there's only 10 packages in total. 9 create just one user/group, and one (qmail, which AFIACT isn't even in Debian) creates six. I'm unsure why these 9 packages need a static allocation, given that every other service just creates/removes them dynamically. Given the miniscule usage of this reserved range, is static allocation justifiable?

The main justification I would have for this change is that keeping
the old 16-bit-constrained assignments fragments the 32-bit range
space unnecessarily.  For checks such as being discussed, having a
contiguous user range makes things much simpler for both us and
admins.  I accept that we can't change things for existing systems
where these are already being used, but it sucks to be stuck with a
16-bit legacy for evermore even for new installs.

I don't think it's practical to ever get rid of the legacy UID range
fragmentation in the 16-bit space.  Better would be to plan a transition to
where we start numbering new user accounts from 65536 by default, instead of
from 1000.

Something probably best left until after Squeeze! I think the simple check we have now will be robust enough until after then.
