I’m using FreeBSD 10.0-RELEASE on my file server, which will double as my package builder. I’d prefer to run Poudriere inside a jail so that all its binaries and configs are confined there, but this is not a supported configuration, and Poudriere requires so many permissions the security benefits would be minimal, and it still encounters trouble.
This shouldn’t be a problem though, as Poudriere won’t expose any services, and the packages will be published by a jail utilizing read-only nullfs mounts.
