[Info-vax] Request description of UFS for VMS person

[JF Mezei]

Someone asked about NFS:

$ cat /disk2/www_main/vms.dir
cat: /disk2/www_main/vms.dir: Operation not permitted

(this is on a directory served by a VMS machine, accessed from OS-X).


And now for te juicy part:

TCPIP> mount dnsf1: /host="brakes"/path="/"/server_type=unix/structure=5
%TCPIP$DNFSMOUNT-S-MOUNTED, / mounted on _DNFS1:[000000]


Back on unix:
$ ls /usr
X11R6           include         libexec         sbin          standalone
bin             lib             local           share
$


And back on VMS:

DUMP/RECORD dfns1:[000000]usr.dir

When you consider that DUMP provides records in a different order than
the "ls" command, it is safe to assume that VMS fully synthetizes the
"usr.dir" file, complete with sorted entries so it doesn't actually list
its contents.

Can anyone tell whether the output of the DUMP/RECORD shows "VMS"
directory contents or would those be of a unix directory file that were
just sorted ?
