gnome-control-center requires modemmanager, which in turn requires ppp, which in turn requires ipv6. What percentage of gentoo installations have a modem? Not really many. Can this be removed?
It can not be removed without ongoing extra maintenance burden in supporting it without modemmanager. It's not really any sort of priority or desire to have that extra burden, as it doesn't really bring any benefits beyond not installing some dependency. If you don't have a modem, you don't have to have that ppp in a working order, much less have IPv6 for it, for which it actually has a USE flag in the ppp package to somewhat disable. This ppp package is taking 940kB of my disk space and that's about it (I don't have a modem either), I haven't even minimized it on any USE flags on purpose. Please note that many people do have a modem or might need it suddenly. This is about supporting mobile data modems mainly (4G internet usb sticks, integrated ones in business laptops where you just insert the SIM, etc), which use this stuff, not some sort of 56kbps dialup. *** This bug has been marked as a duplicate of bug 478204 ***
Thanks. I have decided to remove networkmanager completely from gnome-control-center and use a ncurses interface to manage my network.
I think that's a bad choice, but up to you. If you stick with NM overall, there's nmtui for a ncurses based interface. And nm-connection-editor from nm-applet is a GUI (albeit probably semi-deprecated and not getting much upstream love). And I believe with gnome-shell[networkmanager] you can still do the basics from the top right gnome-shell menu if using gnome3, as gnome-control-center[networkmanager] I think just provides the Network settings panel from the settings panels (where modem managing is on the same panel, so it's easy to disable the whole panel, but not modem network configuration from inside that panel).
