However, I think this can be overcome by having "open" et al. check $HOME/myroot/* first and then /*. Write opens on things in /* could be handled by copying the file first. I do recognize that this is not the way to go for permanently running things, however, I think that this could help when you want to test something quickly on an architechture you only have loaned a user access for but cannot install packages easily. Example: I have (privately for now) a kde package and wouldn't want to have to compile KDE on an architecture just to be able to test compilation and installation of my package. Installing in $HOME might be OK for that, though. For permanent installation, this clearly isn't the right way to go, for temporary deviations to the debian configuration, IFAICT there might be some justification for the approach. (Just like fakeroot isn't intended to be generally used instead of sudo.) Cheers T.
