CRUX 3.7 introduced the possibility of using the \fIrenames\fP array to
prevent automatic unpacking of archives whose original filenames would have
matched the pattern *.(tar|tar.gz|tar.bz2|tar.xz|zip|rpm|7z); in previous
CRUX versions the clunky workaround was to redefine the \fBpkgmk(8)\fP
function \fIunpack_source()\fP and delay that pattern match until
specially-designated source files are given special treatment.
Because this use of \fIrenames\fP is not a very intuitive solution to the
problem of coping tarballs intact, another mechanism was proposed. Starting
in CRUX 3.7.1 you can define a \fInounpack\fP array in your Pkgfile,
containing the on-disk filenames of tarballs that you want copied as-is into
the work directory. Filenames that do not match the pattern
*.(tar|tar.gz|tar.bz2|tar.xz|zip|rpm|7z) will be treated exactly as before;
you never need to define \fInounpack\fP (or \fIrenames\fP) if the pre-3.7
pkgmk behaviour is what you want. During the gradual rollout of the new
pkgmk feature, it is safer to try finding alternative source files that will
populate the work directory appropriately, regardless of which pkgmk the
user has installed. For example: instead of
.B source=(pkg1.rpm pkg2.rpm pkg3.rpm),
distribute a tarball containing all these rpms, and then define logic in
\fIbuild()\fP that lets bsdtar handle each rpm as needed for your port.
