Hi,

Over coffee with a colleague (cc'd) we were talking about the problem of
taking advantage of ZFS over NFS (or CIFS) from a non Solaris machine.
We already have the .zfs/snapshot dir and this is great. One of the
other areas was knowing the settings on your data set are. So enter
.zfs/info which would be an ascii representation of the information from
`zfs get all`.
I can see some problems with this, and it reminds me a little too much
of what happened to /proc on Linux and so a bit uncomfortable about
suggesting.
I share the uncomfort with the /proc analogy.
But Wes' scripting approach seems to be just fine for me. The timestamping
would communicate the SLA of "just a script" versus the magically hacked
nature of pseudo-files.
But being able to poll data out of ZFS over NFS is probably just a minor
issue. In germany, we say: "Give 'em the little finger an they'll want the
whole hand".
So, I assume the next thing a ZFS-over-NFS user would want is to change stuff
over NFS which would then become difficult. Resisting the pseudo-files-as-a-
broken-API-for-changing-stuff urge might then be even more appropriate.
Best regards,
Constantin
