Subject: add experimental pool_deb_get_autoinstalled
X-Git-Tag: 0.6.9~17
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4c4050d44df569525b884be3e752fc54f23a9619;p=thirdparty%2Flibsolv.git

add experimental pool_deb_get_autoinstalled

This can be used to read the autoinstalled package list from
/var/lib/apt/extended_states. Note that the pool must have
the whatprovides hash in place for this to work.
