Well, as i wrote, the existing static /dev is about to be killed anytime soon. MAKEDEV as well -- shouldn't you have it already noticed. Persistency of the devfs entries across reboots was one major point of discussion, and good ideas are still sought. I tend to defend the idea of keeping this outside the kernel, so the device drivers do only create their generic device nodes, while some /etc/rc-started userland script creates the required links (and tweaks the permissions if necessary). Anyway, i'm biased, i have seen something to this avail working on DG/UX. Simply backing it up with cpio or dump and restoring later is *not* the way to go then. > Also, perhaps we should > s/GNU/GNU (& thus FreeBSD etc)/ > in the (formatted) chunk: > The new ASCII format > is portable between different machine architectures and > can be used on any size file system, but is not supported > by all versions of cpio; currently, it is only supported > by GNU and Unix System V R4.

It's the only archiver sanctioned by Posix.2. All platforms that claim support for Posix.2 should have it. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ -- NIC: JW11-RIPE Never trust an operating system you don't have sources for. ;-)
