The noudeb build profile and dh-only rules files

["Theodore Ts'o" <tytso@mit.edu>]

I'm the middle of an effort to simplify the debian/rules file for
e2fsprogs so that someday, maybe, I'll be able to convert it to use
dh.  One of the things which I noticed while trying to rip things out
of debian/rules to make the dh conversion easier (possible?) was the
support for noudeb.

How important is noudeb, and why is defined in the first place?

And will debhelper do the the right thing in terms of filtering out
udeb packages if noudeb is psecified in DEB_BUILD_PROFILES?  If
support of noudeb is free in the brave new dh-only world, that's
great.

If it has to be hacked in manually, how important is it to support
noudeb?

I've tried to do some web searches to answer the above questions, but
I'm afraid my Google-fu has failed me.  So maybe this is something
that can be documented in a few places, including the debhelper man
pages, and perhaps, in the BuildProfileSpec Debian Wiki page?

Many thanks!!
