Hi Toomas,

1) Removing everything under /var/pkg/cache/ directory causes no 
troubles (so I did it and rebooted systems - no issues)

2) Checking usage of 15G under /var/pkg/publisher/openindiana.org (1st 
column is size in bytes) - as you may see, no core files are found:

3) I would like to know, why (in this biggest sub-directory) I get eaten 
10 MBs almost everyday? Any idea?
