In the yum-utils package there is a helper script called

But the list needs to be reviewed line by line because not all
packages that lack dependencies should be removed, such as the
kernel, which is not depended upon by another package :)
Hmmm, tried that but it didn't pick up many of the packages that I
thought it would. There were a bunch that I believe were orphaned
when I upgraded with fedup from 18 to 20 but the Qt packages that
were pulled in by the wsjtx install and all the 32-bit
compatibility packages were not listed.
Well, sometimes it's just nomenclature :) With yum/rpm orphans are
packages that no longer reside in an available repository so ALL
locally installed packages will be in that list.
Yes sorry about that, I realized as soon as I clicked send that I should
have said leaves rather than orphans.
After an upgrade you want to use the --problems and --dupes options to
do some housekeeping.
OK, they list nothing.
Sometimes yum remove seems to know what were installed as
dependants other time it seems to forget and leave the leaves
installed.
Well, it's basically that it works in one direction only. If you
install a -devel package it will install all the required base
packages, if you try to remove the -devel package it doesn't know you
don't need the base packages anymore, but if you try to remove any of
the base packages, it MUST remove the -devel package or there will be
dependency issues.
OK, but what about chains of base packages. The Qt5 multimedia package
requires several other packages and it was pulled in by installing wsjtx
as "Dep-Install" yet none of them come up with 'package-cleanup
--leaves' after I 'yum remove wsjtx'. So what is causing the Qt packages
to hang around?
I've just run 'yum autoremove' and that has dropped the Qt 5 chain.
Maybe I should have just run 'sudo yum autoremove wsjtx' in the first place.
It seems that the 32-bit compat libs are not handled properly by these
tools as they never seem to get auto removed. I suppose they must be
protected in some way.
Thanks,
Richard
