I did some testing with this, and it appears that the postinstall scripts aren't being run in the right context when the packages are installed! Specifically, our cfengine package runs "cfkey" if a particular file doesn't exist, and creates it. That doesn't happen when a zone is installed. But if I remove and then re-add the package (from the same source) it works properly. To show the difference, here's output from execsnoop -Z when the zone is installed: global 0 8174 8173 /sbin/sh /zones/mail/root/var/sadm/pkg/CSEEcfengine/install/postinstall and when the package is reinstalled: cfengine 0 8348 8342 /sbin/sh /var/sadm/pkg/CSEEcfengine/install/postinstall ... ypmaster 0 8359 8353 /sbin/sh /var/sadm/pkg/CSEEcfengine/install/postinstall ... mail 0 8371 8364 /sbin/sh /var/sadm/pkg/CSEEcfengine/install/postinstall
DTrace shows the postinstall scripts executing, and files being opened. I have opensnoop -Z and execsnoop -Z logs for an entire zone install if anyone's interested.

If I specify SUNW packages that include the requirements to chroot as dependencies of my packages, will chrooting in my postinstall scripts be safe? Thanks! Will
