Yes, we are using the RH kernels as a base, the limit is supposed to be 1200+ but my experiments have shown it to be just shy of 800. Or maybe that results is due to a bug in the autofs code. I think the real solution to this problem is Richard Gooch's devfs and kernel 2.6. It's anyone's guess when there will be a distribution using both of those but I think Fedora might be the first.

(This includes proc, autofs, nfs..). This is because pseudo-block filesystems all use major 0, and each have a different minor (thus the 256 limit). There are however patches floating around (look at SuSe's kernels, I'm not sure about RH) that allow n majors to be used (default 5). This gives you 1280 mounts, a big step up :) Mike Waychison _______________________________________________ autofs mailing list [EMAIL PROTECTED] http://linux.kernel.org/mailman/listinfo/autofs
