+
+Well, I'll attach my work to the bottom of this message and let you judge it
+for yourself.
+
+The config.cache I'm trying to generate here is not equivalent to what
+a configure script outputs. The only values I'm including are those which 1)
+are no-brainers on any glibc-based platform, 2) are questions we need to force
+a particular value for regardless of the kernel being built against, or 3) are
+questions about specific bizarre features of proprietary Unices that we'll
+always get an answer of 'no' to.
+
+I've removed all of the config.cache variables related to headers, or to
+checks for particular libraries; I think it's pretty safe to assert that glibc
+provides basic C functions like select(), setenv(), and waitpid() on all our
+build targets, but I think it's less safe to assert that they'll always be
+provided by particular header files.
+
+So the config.cache won't automatically be updated with answers to new
+configure tests, but it also doesn't need to in order to be useful. There's
+really only a handful of variables in there that we /need/ in order to
+guarantee correctly-built packages, and if you want to leave out everything
+else, that's perfectly ok too. Everything from the fifth stanza on down is
+just a build-time speed-up for some of the slower architectures. Well, it
+also has the fringe benefit that the packages will FAIL to build if someone
+tries rebuilding for a really bizarre (non-Linux, non-glibc) architecture. I
+see that as a plus :), you may disagree, but in any case my next trick would
+be to add a global variable developers can set to bypass the provided
+config.cache.
+
+
+It is a little artificial, but the whole point of .debs is to be able to build
+binaries in a controlled environment. Right now, we don't really have control
+over what happens in the autobuilders. We have even /less/ control over what
+happens in a stable release: it's been two weeks now since I built binaries
+for bug #94380, and they haven't been uploaded to security.d.o yet. I'm
+guessing they won't be uploaded until Wichert is back from vacation, either --
+which is fine, but it would be nice if we didn't have to worry about
+mis-builds by the security team, or about putting the security team to extra
+trouble after the fact to get packages fixed.
+
+With a pre-loaded config.cache, we can ensure that bugs of this kind don't
+happen in woody. We can take the arm autobuilder problem into our own hands,
+and not have to worry about quirkiness in the build environment. We can even
+close bug #109773, since we no longer have to worry about detecting the
+setuid() routines.
+
+
+So to me, it definitely seems worth it. But you're the maintainer, and I
+won't ask you to put anything in the package that you're not comfortable with.

+
+It could be. There are arm packages for 2.2.1a-1, so at /some/ point the
+autobuilder was able to pass the locking test.
+
+

+exact reference for the arm autobuilder is at
