oh, an interesting thing about apt-get is that it seems to be the only program I know of that seems to write files via mmap. (i.e. SHARED/WRITE), and therefore will not work on file system's that don't support shared write mappings (i.e. gfs/ocfs2 at least). _______________________________________________ unionfs mailing list [email protected] http://www.fsl.cs.sunysb.edu/mailman/listinfo/unionfs
