We=E2=80=99re building product that uses bhyve to run virtual machines = and we wanted to use UUIDs as names. UUID with hyphens has 36 characters and without it has 32 characters. = Can this limit be increased to 33 and=20 ideally to 37 or more characters? For comparison qemu-kvm+libvirt allow for virtual machines with names = that are over 240 chars. =E2=80=94 Regards, Mateusz Kwiatkowski=
