[ just to recap, FAM-2 says:

FAM-2: Provide an environment such that migrating (particularly
       GNU/Linux) users will be familiar with the utilities
       available, while preserving the binary compatibility 
       story that people want and expect. ]

Is this the sort of thing you mean:

timf at haiiro[883] ps aux
The command "ps aux" is unavailable or has different
syntax in OpenSolaris.
You might want to use the following instead - 
Example: ps -ef

See the ps(1) or pargs(1) man page for more information.
timf at haiiro[884] top
The command "top" has is unavailable or has different 
syntax in OpenSolaris.
You might want to use the following instead - 
Example: prstat 1

see the prstat(1m) man page for more information.

A gross hack, and doesn't work if people run /usr/bin/tar, for example,
but it that enough, or do we require people put /usr/gnu or /usr/sfw/ in
their paths and be done with it ?


I prefer the idea of a GNU zone, _iff_ there could be seamless desktop
integration with the zone, so at desktop session startup time, the user
actually gets presented a VNC session into a zone that's configured
appropriately to provide that GNU-like environment, rather than a
Solaris environment.

I believe that would keep everyone happy - then at installtime, you
should be able to choose whether you want Solaris installed as the main
userland personality, with a GNU zone, or the other way around.

I'm interested in how we could plan to solve this problem.

	cheers,
