On my x86_64 desktop I get:
# 2113 package names, 557 Leafs, 158 leftovers, 266 lines
...however I get a bunch of packages that don't exist (like -prctl in
base), fixing that I get:
# 2113 package names, 557 Leafs, 151 leftovers, 259 lines
...and 259 is a big improvement over 2k, but it's more than I thought it
might be. Post patch my RHEL-5 server gives:
# 205 package names, 57 Leafs, 43 leftovers, 54 lines
...which is even worse (only group is @base, and that has -9).
