riiiiight, but that makes a nasty circular dependency I thought we should avoid at any rate ? Shouldn't libc-bin rather conflicts with bad version of the libc ? > Also consider what would happen if ldconfig does go missing.

Though, that part seems to be quite brittle, and I assume we could use another tool than else, you are right, the only thing we have to be sure, is that *a* libc-bin is extracted before libc6 postinst runs, and that should always be OK, since libc6 depends upon libc-bin. -- ·O· Pierre Habouzit ··O [EMAIL PROTECTED] OOO http://www.madism.org
