True - but is there any static linking going on in fact? There isn't much of it about these days (flex does it IIRC, and no doubt a few other bits of software for various reasons). I have often wondered how much 'old code' seeps through in a project like this. In theory it should be very little. I've never checked the practice. > This presents a kind of > chicken-and-egg problem.

That would require there not to be lots of circular build-dependencies in Debian, such that there was a linear order to build things in. That's not actually the case (see http://wiki.debian.org/CircularBuildDependencies). In practice simply building everything twice will probably do the trick. > To accomplish creating all the packages for a minimal install of Debian armhf, > it means that not only do I need to rebuild all packages pulled in by > debootstrap, but all packages those packages link against (which can be found > by build-dep). This will be an interesting exercise. The set of packages you install and the set of packages linked-against will be the same, except for static linking, and I beleive that to be very rare, quite possibly non-existent in a base install. So I don't think this issue meaningfully changes your problem-size.
