I have a few older systems (~6-10 years in use) that have no system list. Over the years there have been various disasters and methods of managing the software with the result that I have had to run regenworld amongst other things.
So, how can I restore "system"? - the machine below has 115 packages listed by depclean, and with a couple I know as critical - but its the ones I dont know that are worrying me :) BillK myth1 ~ # emerge --depclean -vp * Depclean may break link level dependencies. Thus, it is * recommended to use a tool such as `revdep-rebuild` (from * app-portage/gentoolkit) in order to detect such breakage. * * Always study the list of packages to be cleaned for any obvious * mistakes. Packages that are part of the world set will always * be kept. They can be manually added to this set with * `emerge --noreplace <atom>`. Packages that are listed in * package.provided (see portage(5)) will be removed by * depclean, even if they are part of the world set. * * As a safety measure, depclean will not remove any packages * unless *all* required dependencies have been resolved. As a * consequence, it is often necessary to run `emerge --update * --newuse --deep @world` prior to depclean. !!! You have no system list. !!! Proceeding is likely to break your installation. Calculating dependencies... done!
