I'll do some GAR integration to make this as straight-forward as
alternatives.

Great! thanks.

However, all this doesn't bring us close to NFS-sharing when
alternatives are used. Suggestions, gentlemen?

I will repeat my question/request, that before people can make
suggestiions for solutions, they first need to be better informed on
exactly what our "alternatives" system does in /etc/opt.

With a reminder that the "best behaviour" would presumably be to use /etc/opt as
an *optional*, but not *required*, enhancement.

ie: If /etc/opt was normally used to preserve user choices across
upgrades... but without it, some kind of sane "default" was made
visible... then in the NFS shared /opt/csw situation, it would be
acceptible to lose the "preserve choices", as long as it just went
with the default behaviour, rather than "I'm not going to work now".

Alternatives makes a link from the thing to choose to /etc/opt/csw/ alternatives/<pkg>. There is another link to the final file which is automacially handled by alternatives. If on the source location the link is not pointing to /etc/opt/csw/... the
alternatives system doesn't touch it as the link probably has been done
manually. In general it is possible to hardwire it to minimal with a specific class. The idea would be to have a cas script that reads the csw.conf if it is NFS shared or not and when in NFS-share-mode it makes one static link without alternatives. I could add this to the existing alternatives CAS. Comments?


Best regards
