Re: loader.conf and rootdev option for memory disk

But your previous post shows rootdev= there didn't work, and needed setting vfs.root.mountfrom=. OTOH, rootdev= is reported to work in efi/boot/freebsd/loader.env (with efi loader) on freebsd-users-jp ML (as it's Japanese ML, in Japanese) this year. So /boot/defaults/loader.conf

Re: ULE realtime scheduler advice needed
