The Debian policy manual section 10.2 covers users and groups.
Specifically, the uid/gid numbers 0-99 are explicitly assigned
via base-passwd, 100-999 are dynamically assigned system uid/gid's.
So, it seems that any package that doesn't need an explicit uid/gid
gets the next available system uid/gid via adduser --system.
I would assume that system packages are only thought to need
consistent id's when they actually own files (vs. root.root
config files). One hundred id's isn't very many to go around.
