Here are just a few notes from my current Gentoo update session:
- eselect profile list - Need to update to the newest "10.0" profile, specifically the "desktop" profile. INFORMATION
- KDE 4 guide
- libxcb update
- rm /var/cache/revdep-rebuild/*.rr
- Convert ext3 to ext2 for the solidstate netboot
- Verify /etc/localtime (diff with /usr/share/zoneinfo/...) and update /etc/conf.d/clock (see gentoo handbook chap 8 Configuring your System).
- for problems with e2fsprogs and harddrive/file timestamp issues (files edited in the future) see this
- OR, install the stable version of e2fsprogs and sandbox. Later problems with libblkkid.so.1 require a "revdep-rebuild"
- add "emergency" to grub to boot into single user mode (or "s", "S", "single", or "-b")
- sdl-image update error (no solution yet) - trying by doing -gif and -mmx for sdl-gfx
