I tried some patchadd that didn't work for me (I had had success earlier). The strange thing is, that the error message could not be found in Google!?:
[i]Validating patches... Loading patches installed on the system... Done! Loading patches requested to install. Checking for consistency of zone attributes between patch packages and installed packages [...] Failed to do zone attributes check [/i] I entered the last line and got 0 results. I also read man patchadd and tried with -G, no change. This message posted from opensolaris.org
