Rayson,
NT kernel has the filter driver framework:
http://www.microsoft.com/whdc/driver/filterdrv/default.mspx
It seems to be useful for things like FS encrytion and compression...
is there any plan to implement something similar in Solaris??
The Availability Suite product set
(http://www.opensolaris.org/os/project/avs/) offers both snapshot and
data replication data services, both of which are built on top of a
Solaris filter driver framework. By not installing the two data services
(II and SNDR), one is left with a filter driver framework, but of course
with no filter drivers. If you are interested in developing an
OpenSolaris project for either FS encryption or compression as a new set
of filter drivers, I will post relevant information tomorrow in
