Yes, USE="" is a good start. However, one has to take into account that portage adds use flags while going through the emerge process. For example, if you install mysql in order to use it with amaroK, mysql would, after that emerge be turned on as a global useflag. If one wants to keep a clean system, they have to compensate for this behaviour, and check, at the end of an emerge process*, that the list of useflags has remained unchanged. *(NOTE : not at the end of the merge of every single package, but at the end of the merge of one list of package, since emerge reads the USE variable once at the beginning of the merge process, even if there are 20 packages on the list). Oh, and unless you are a developper, there are some defaults useflags you can turn off, like "fortran", for example. One last thing, I would suggest using "euse", which is part of gentoolkit, to check the meaning of a useflage. It searches both use.desc and use.local.desc. -- Jonathan > > Timothy A.
