DON'T know if this can be tweaked for what you need but "apt-cache
showpkg" provides reverse depends, *sometimes* anyway.. I just tested
it on something I do NOT have installed (the puzzle game Palapeli),
and it still worked. I've been *a-suming* it will provide what you
seek based on what repository CHOICES each user has personally
specified in sources.list (for APT)....
Ok, I just got the bright idea to try it on mine and got this back:
+++++++
Reverse Depends:
udev:i386,systemd 28
systemd:i386,systemd
udev,systemd 28
systemd-sysv,systemd 44-11+deb7u4
systemd-gui,systemd 44-11+deb7u4
libpam-systemd,systemd 44-11+deb7u4
pcscd,systemd
live-config-systemd,systemd
lighttpd,systemd 29.1
++++++++
DISCLAIMER because of the inevitable question: No, I have no idea what
I have at this point. I keep saying I think my (first) debootstrapped
distro is picking and pulling at things behind the scenes. Something
compatibility wise is just not right ever since I went that route.
My sources.list is pulling by distro name (and not stable, testing,
etc) so I've been *a-suming* Jessie is not involved in apt-cache
queries. A quick peek at the Net says that should be right, that my
CHOICE of repositories should rule what results my apt-cache queries
bring. If someone can think of a package that is ONLY in Jessie, I
could test it to see if anything pulls up...
Have had to take some (cognitive) down time and now trying to get back
into the swing of things. Just a little bit ago set back in motion
finishing out that debootstrapped [install] to FINALLY catch up to
speed with you all. Tell you what, this whole systemd deal..... am
feeling more lost right this very second than ten, fifteen years ago
when Linux was first hitting my radar via incidental mentions by
fellow list members over at W3C (w3.org).. *grin*
