I discovered this when using emerge command. When I use 'su -' command to switch to 'root' account everything work fine, however when I use 'sux -' command to switch to 'root' account emerge always complains that 'HOME' variable is not set. I found that some other tools also have problem with 'HOME' variable asfter using 'sux -' command and never seen that after 'su -'. Therefore I guess 'sux -' incorrectly sets variables. Oh, and after 'sux -' command when I execute 'set' then I can see correcly set 'HOME' variable, but for some reason it is not visible for some applications. Reproducible: Always Steps to Reproduce: 1. sux - (to switch to root account from ordinary user account) 2. emerge -Du world (I seen emerge complains about HOME many times) Actual Results: Although emerge work fine it very often displays message: HOME not set..... Expected Results: I think behaviour should be exactly the same as after using 'su -' command - no problems with HOME variable.

Explicitely fixing $HOME now in -r1, but the same problem could persist with other variables. Ok, since it took month for someone to notice this HOME problem we will maybe never see a bug report for others :-) Thanks for reporting!
