Looking through the kernel source I've found directories for both ufs and ffs, but not ufs2 (/sys/ufs/{ufs|ffs}/). Also, it seems like Solaris and/or other commercial unices also used ufs, is this the same ufs used in BSD and how does this relate to ffs and ufs2? --=20 I sense much NT in you. NT leads to Bluescreen. Bluescreen leads to downtime. Downtime leads to suffering. NT is the path to the darkside. Powerful Unix is.
