The May issue of BSDMag (available for free download here) has two articles about PC-BSD.
Kris Moore has an article â€œA Fresh Look for the Warden for PC-BSD 9.1â€³ on pp. 6â€“9. Warden is a GUI tool for managing FreeBSD jails and has been rewritten for 9.1. New features include the ability to add multiple jails, the ability to create FreeBSD jails or ports jails (which use nullfs to allow you to safely install and run apps on your PC-BSD system), and the ability to export and import jails.
Jesse Smith has an article â€œIntroducing EasyPBIâ€“Making PBI Modules With a Few Mouse Clicksâ€? on pp. 18â€“19. EasyPBI allows one to convert an existing FreeBSD port into a PC-BSD PBI with an easy-to-use GUI.
