typically aren''t the kind of thing you can update without updating the
kernel itself.  Never thought of just updating the fs independent of the
kernel... or have I misunderstood something altogether?

When you ''pkg image-update'' it will update everything
consistently so
the kernel is updated as well as all the matching commands and libraries.

Unlike Linux the OpenSolaris kernel isn''t separate but is part of the
same source base as libc and many of the core commands.   The builds in
the /dev repository carefully lined up collection of all the source
bases (consolidations) to form a build.

There is on OpenSolaris equivalent to grabbing just the kernel source
for Linux.
