If the local administrator or package B's preinst script have registered
a diversion for one of package A's files, they an alternative
implementation for that file -- or a wrapper script in the case of
executables. Renaming of the file takes effect immediately if
dpkg-divert is called with --rename or when package A is upgraded.

(I use this feature for a local modification to my build chroots that
calls dpkg using the eatmydata wrapper.)

I think that the description in
https://www.debian.org/doc/debian-policy/ap-pkg-diversions.html is
better than the manpage.

Wouldn't the diverted filename then be used in the ext2 or chroot
building code?
