5 I would probably rebuild the toolchain, then emerge -e system, then emerge -e world. I used the emwrap.sh script found in the forums to help with this on my Sunblade 100. I realize the jury is still out on this (and particularly this script), but it made sense to me given how everything is linked. I am still a little confused on the proper arguments to use (horrible documentation), but I believe emwrap.sh -Sb1 will rebuild the toolchain, then the system minus the toolchain. Then running emwrap.sh -W takes care of the world.

7 Running though this exercise solved a lot of the general weirdness that was going on after I switched from 2006.0/2.4 to the 2006.0/2.6 profile.

59 OK, are you suggesting that I stick with gcc-3.4.6 then?

61 Also, if I wanted to revert to a NON-SELinux system, would switching
62 my profile and running an `emerge -DuatvN world' work? Or am I
63 looking at a complete reload at this point?

75 OK, that may explain the funkiness I'm getting with the keyboard under
76 the 2.6 kernel then, unless I'm misunderstanding you.
