Only the `/lib' from the packages listed in `systemPath'.  Currently
that represents 61 `.so' files here...

Yes, although it destroy it as much as `$currentSystem/bin' destroys
purity for executables.  :-)

That'd be the best thing, but how would you achieve it?  The
`pathsToLink' attribute is coarse-grain and doesn't allow us to ask that
only `/lib' from a subset of `systemPathList' be symlinked.


BTW, this whole hack still isn't sufficient: NSS modules, somehow,
aren't visible from the `nix-worker' chroot, which makes it impossible
to build in a chroot because DNS lookups systematically fail.

What am I missing?  I was under the impression that `systemPath' was
mapped into the chroot.

Thanks,
Ludovic.
