The biggest compatibility problem of OpenSolaris (compared to Sun Solaris)
is the fact that libm is not part of OpenSolaris.
In case you don't know, it took me a full month already to work on
FreeBSD's libm in order to be halfway compatible with Sun Solaris and I am not
even shure about the effort that would be needed for a mostly 100%
compatibility. I am definitely interested in a UNIX centric OpenSolaris
distro. Do not expect people who work on Linux centric Open Solaris distros
to put a similar amount of work into compatibility issues.

I am not sure whether appcert(1) is sufficient to check for the compatibility
ussies we will see on typcal OpenSolaris dustros.

So judging from above, do you consider libc to be "unstable" as it
calls system()'d or exec()'d utilities to support basic Solaris
features like smf?
