[zones-discuss] Parameters in /etc/system in the zone
Hi, All! I have a zone question - to my knowledge /etc/system in a zone has very little meaning, as these are kernel parameters. But still certain things can be set using this file. Is there a list of parameters for /etc/system, that work in a zone? I am asking in general, not for specific issue... Thanks!

Re: [zones-discuss] Parallel mount question
After removing NFS, we got yet another corruption - I just heard they use Samba on this file system. So, let me ask the question - Samba is supported in zone, running on LOFS - is this correct?

Re: [zones-discuss] zonecfg question
Yes, John, that's my understanding too - zonecfg is supposed delete both the entry in the index file, and the xml. But, somehow we ended with this awkward status. It makes sense to me if zonecfg detects such status, to send one extra Status missing - are you sure to delete?-type of message, and remove the xml...
