For postgres you've to turn on the jail.ipc. This is basicly not so bad, but definitely reduces security. For samba/nfs/ldap/nis and asterisk I don't have the experience, but if they not need ipc, they'll run fine out of the box. In jails I suggest that you mount your ports tree with some nullfs mount. With this you'll save some hd capacity. (The installed port list is in /var, not in /usr/ports.) In jails you can't do resource control, so keep that in mind. Regards, Andras
