Yes, you can run JumpStart inside an S11 zone, I use JET this way now.
You need to add the DHCP services (for PXE boots). Also thre is no flar command, so if you use JET or have any scripts that reference it just grab some flar info output and have a script (called flar) echo it out :-)

read-only with root access. Use the "zfs set" command to
set the sharenfs property for file system /aipool/jumpstart as follows:
Use ro and either anon=0 or root=oradb04 for /aipool/jumpstart.
This must be fixed and /aipool/jumpstart shared
before oradb04 can boot.
