Is there any way to prepare a listing of ebuilds that a build of gentoo should have so that the installation of a system can be somewhat pre-determined? Almost like an ebuild kit?
I would like to maintain a listing of packages that I want for a server of mine, but I want to make sure that I'm trimming any excess garbage that comes in.

So that's going to give me the output of a whole system build? (Obviously --pretend will allow me to fake the process & get the same results?)
Does that include the essentials that I may or may not be able to strip out?

Yeah, --pretend will do fine. emerge -ep system shows the list of the basic system, not everything on the system. emerge -ep world does that.

Alright, forgive me for not being the brightest - but how will this help me in creating a highly customized ebuild set for a system?
What I'm looking to do is really get into the details of trimming the fat off my server system. Getting only what I need, and as a side-question, how can I lock an e-build to a particular version of a program? For example, how can I lock my system's kernel to 2.6.X.Y? Or maybe say lock MySQL?
Lots of things I want to do basically along the lines of stability during updates and not having broken configuration files.

How would I go about locking ebuilts to a specific version?

You could create a custom portage snapshot (or use an existing one). Then as long as you don't change the snapshot, none of your packages will get updated to a different version. |

| Use either emerge --oneshot =app-type/program-version or you might try masking the versions below and above.[/b] |

Put the package version above that one you want to lock in /etc/portage/package.mask
Example: if you want to stay with gcc 3.3 put >sys-devel/gcc-3.3.* in /etc/portage/package.mask, this way any version grater than this will not be emerged.
See man portage for detailed info.
cheers. |

Perfect, I like revertex's solution. That's exactly what I'm after for the version locking.
This is one of the reasons why I kind of hate portage documentation. Nobody wants to take the time to publish the best-practices. Just a bunch of cryptic nonsense.
