Summary:                    --set does not work
Description: 
during testing the new apache2 package I wanted to change the alternative:

/opt/csw/sbin/alternatives --display httpd
Installed alternatives for httpd are:
/opt/csw/apache2/sbin/httpd httpd /opt/csw/apache2/sbin/httpd.prefork 100
/opt/csw/apache2/sbin/httpd httpd /opt/csw/apache2/sbin/httpd.worker 50


/opt/csw/sbin/alternatives --set httpd /opt/csw/apache2/sbin/httpd.worker

ln: cannot create /etc/opt/etc/alternatives/httpd: No such file or
directory

I added an extra debugging line too to print the content of $line just
before the set_link call.

The altneratives stuff is pretty stock.  I used the built in GAR support
for this and have a file /opt/csw/share/altneratives/apache2 containing:

# cat /opt/csw/share/alternatives/apache2 
/opt/csw/apache2/sbin/httpd httpd /opt/csw/apache2/sbin/httpd.prefork 100
/opt/csw/apache2/sbin/httpd httpd /opt/csw/apache2/sbin/httpd.worker 50


This is, afaik, a valid file.  Both altnernatives are being shipped in the
same package, so the altnatives file has 2 lines.  Anyway, I still think
alternatives is doing something wrong here...debug output:

# DEBUG=echo alternatives --set httpd /opt/csw/apache2/sbin/httpd.worker
