Re: System crash

[Robert Nestor <rnestor%mac.com@localhost>]

My NFS is on a DS218+ Synology NAS which I believe is based on a version of Linux.  FreeNAS is based on FreeBSD I think, if that makes any difference.

Could be something I haven’t configured properly on my NAS, but everything else has been working fine for the last couple of years and it’s where I have /home mounted which works for accessing files from Mac, Linux and NetBSD.
