Maybe using sources.debian.net to find this list: $ curl -s http://codesearch.debian.net/results/5d29ff30a4ba878c/packages.json | jq -r '.Packages[]' tcl8.4 openjdk-7 zfs-fuse libguestfs zfsutils kfreebsd-10 php5 glibc apache2 nodejs libreoffice ust systemtap gjs libeatmydata qpid-cpp haildb icedove ctfutils libmemcached openjdk-6 kfreebsd-kernel-headers gearmand openjdk-7-jre-dcevm db5.3 freebsd-libs xorg-server pgtop mozjs24 gcc-4.9 gnat-4.9 tcl8.5 fpc erlang mono tcl8.6 db gdb wine-gecko-2.24 iceweasel mozjs hhvm wine-gecko-2.21 mysql-proxy However, the list is incomplete since the header inclusion doesn't have to appear for a package to have support for systemtap. For examples, lldpd is not in the list while it has support for it. It just uses "dtrace" to generate the appropriate code. libvirt is another example like that. We could search for packages having a ".d" file with "provider" in it: $ curl -s http://codesearch.debian.net/results/3afc484d5a9a1911/packages.json | jq -r '.Packages[]' iceweasel qtwebkit mozjs24 icedove wine-gecko-2.24 postgresql-9.4 tcl8.5 xorg-server inn2 libvirt db julia webkit2gtk gjs ruby2.2 inn openjfx mono tcl8.4 perl kfreebsd-10 libmemcached php5 ruby2.1 db5.3 dnscrypt-proxy pcp mozjs pike8.0 nodejs cjs xen qtwebkit-opensource-src ghc moarvm zfsutils openjdk-7-jre-dcevm mysql-proxy nginx glib2.0 apache2 erlang wine-gecko-2.21 clisp nsf lldpd memcached tcl8.6 libuv mariadb-10.0 systemtap > Then it looks like you may need to provide the information which architectures > have systemtap support.

An example for this might be from the java-common > package /usr/share/java/java_defaults.mk As for support, we could provide an arch all package depending on systemtap-sdt-dev only on architectures where systemtap works (is that authorized?). And a .mk with some appropriate variable that could be used as a conditional. Also, why is this bug marked as important? It's more a wishlist, right?
