How to bootstrap a DU3 zone
To bootstrap a DU3 non-global zone you need to edit /etc/apt/sourses.list. The file contains follow lines:
#deb https://apt2.dilos.org/dilos du3-unstable main contrib non-free
deb https://apt2.dilos.org/dilos du2-unstable main contrib non-free
deb https://apt2.dilos.org/dilos dg2-unstable main contrib non-free
Uncomment line 1 and comment line 2:
deb https://apt2.dilos.org/dilos du3-unstable main contrib non-free
#deb https://apt2.dilos.org/dilos du2-unstable main contrib non-free
deb https://apt2.dilos.org/dilos dg2-unstable main contrib non-free
Install a zone using regular commands (zonecfg, zoneadm). Do not forget to revert the changes in the sources.list file when a non-global zone has been installed.
