yum erase unused dependencies

[Bill Davidsen]

I recall last year a discussion of using yum to remove unwanted packages, and 
tell it to remove only dependencies which were used by no other package. I can't 
seem to find how that was done in my notes, could someone give me a pointer to 
the method?

which can be easily optimized by a small meta-package
and i maintain a bunch of them to have several machine
types quickly installed and any unused package removed
which makes upgrades and de-duplication-backups so
much faster

last but not least you get rid by no longer required
crap if you list there only base-packages without
their specific deps and this is one reason why ton
of years ago installed production servers are as
clean as a fresh install

And let's not forget "yum history undo …", too, since it is the much
cleaner solution for the occasional "install something to take a look and
remove it again afterwards" scenario.

Pure leaf package removal bears the risk that you remove something that no
other package depends on but _you_ need it.

Of course. That's common practice in some places. It also serves as a guard
against not well-tested Obsoletes (or a packager introducing or reverting
subpackages).

package-cleanup can also be useful in this context.

you could add the following to /etc/yum.conf
"clean_requirements_on_remove=1"

Thank you! It was a plugin, which is why I didn't see it. That will do the
trick.
