[gentoo-user] Overlays - mask everything except a specific package?

[Mark Knecht]

Hi,
   I'm looking for a ways to:

1) List all contents of a specific overlay including version numbers.

2) Mask everything in an overlay except exactly what I actually want installed.

   Anyone know how to do this?

   For instance, I use the init6 overlay to get handbrake but I don't
want to use nvidia-drivers & nvidia-settings from the init6 overlay
even if their version numbers are higher.

   Clearly, I can play with masking specific package revisions, but
that's a lot of work and doesn't clearly say where I get a package
when the version numbers are identical.

Thanks,
Mark
