It plays well with the original v4 and your v3. And yes there are unusual problems that I cannot nail. However, it is not at all clear whether they are caused by my kernel patch, the autofs daemon or nfs. Until the nfs client is rock solid I will probably not nail any of the problems. That said we need this functionality in the automounter. Linux will not cut it in the enterprise without it. At least I have something to work with! -- Ian Kent <[EMAIL PROTECTED]> _______________________________________________ autofs mailing list [EMAIL PROTECTED] http://linux.kernel.org/mailman/listinfo/autofs
