Unfortunately, there's no easy (or supported) way to do this at this time.
However, the totally unsupported and you get to keep all the pieces if
it breaks algorithm for it would be something like:
do_not_remove = {}
for each package FMRI listed by "pkg list" (no options!):
name, version = parse_fmri(package_fmri)
name = urllib.urlquote(name, "")
version = urllib.urlquote(version, "")
do_not_remove[name] = version
for name in ls of "/var/pkg/pkg":
for version in ls of "/var/pkg/pkg/<name>":
if name not in do_not_remove:
remove "/var/pkg/pkg/<name>"
elif version != do_not_remove[name]:
remove "/var/pkg/pkg/<name>/<version>"
The basic idea is that manifests for packages that aren't installed can
be removed.
Eventually, the pkg(5) client API will handle this automatically for
clients:
http://defect.opensolaris.org/bz/show_bug.cgi?id=8035
However, remember that if you remove the files from the current BE, that
won't really save you any space because previous BEs still have them.
So only once all BEs have had the files removed will you see a space
savings.
