Since Cochard-Labbé preferred to stay with a FreeBSD-based system, he and Theile agreed that Theile would develop his Linux version under a different name; that name was initially coreNAS, but within a matter of days Theile discarded it in favour of ''OpenMediaVault''. Meanwhile, FreeNAS still needed to be rewritten and maintained. To accomplish this, Cochard-Labbé handed development over to
