I have an Alpha with one disk and two root filesystems.  The root
filesystems are on da0a and da0f.  I want to be able to boot either
one, but I can't seem to find the magic recipe to boot from da0f.
From man loader, I would expect this to work at the loader prompt:

    unload
    set currdev=disk0f
    set rootdev=disk0f
    load /kernel
    boot

That loads the correct kernel (the one on da0f) but the kernel still
thinks its root filesystem is da0a.  I tried adding

    set boot_askname

and (next try)

    set boot_askname=true

in an attempt to get the kernel to let me tell it which root
filesystem to use.  That had no effect.  I also tried adding "-a" to
the boot command, again with no effect.

Is this just broken, or am I doing something wrong?

John
