Warner & Co, Great job all! Been wanting this for years, very excited to see it start landing :) One question, if we switch to Lua loader in TrueOS, do you know if the ZFS boot-environment menus have been implemented / tested yet? -- Kris Moore Vice President of Engineering iXsystems Enterprise Storage & Servers Driven By Open Source _______________________________________________ firstname.lastname@example.org mailing list https://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
