Bug 873402

You cannot 'rpm -e ModemManager' the package?  It's installed by default but it should not be required by any other package.

# yum remove ModemManager

So the answer is no, NetworkManager depends on ModemManager

help?  

KDE does not depend on it, so uninstalling it worked for me, so I have not tried this.

That's like a boomerang. You throw it away and it returns later and hits you. If you rename or remove that file, it will get there again with next package update. It'll break your setup and you'll have to find out what's wrong (because you already forgot).

Ah, we removed the dep for Fedora 18 and later.  But since MM is in comps for f17+, I think we can remove it from the next NetworkManager update for F17 too.  I've removed the dep in package git.

This message is a reminder that Fedora 17 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 17. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as WONTFIX if it remains open with a Fedora 
'version' of '17'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version' 
to a later Fedora version prior to Fedora 17's end of life.

Bug Reporter:  Thank you for reporting this issue and we are sorry that 
we may not be able to fix it before Fedora 17 is end of life. If you 
would still like  to see this bug fixed and are able to reproduce it 
against a later version  of Fedora, you are encouraged  change the 
'version' to a later Fedora version prior to Fedora 17's end of life.

Although we aim to fix as many bugs as possible during every release's 
lifetime, sometimes those efforts are overtaken by events. Often a 
more recent Fedora release includes newer upstream software that fixes 
bugs or makes them obsolete.

Fedora 17 changed to end-of-life (EOL) status on 2013-07-30. Fedora 17 is 
no longer maintained, which means that it will not receive any further 
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of 
Fedora please feel free to reopen this bug against that version.

Thank you for reporting this bug and we are sorry it could not be fixed.

I think this has indeed been fixed since f17/f18 times. And there's now a -wwan subpackage which depends on ModemManger in f21, for those who need it, I think.

Disabled on RHEL 6 so that modem-manager is no longer executable:

chmod ugo-x /usr/sbin/modem-manager
