Subject: Re: Active slice, only for a next boot

Idea is ...
I have i.e; 3 slices, of which first is active.
Now I wana set slice 2 active, but only for a one/next boot.
Once slice 2 is booted and system is shutdown or rebooted, once again,
first slice is active and booted, without user's intervention.
Is this possible or should be implemented?

nextboot(8) USED to do this before it was broken by someone to "look into the filesystem" for it's next boot hint which is obviously broken if you are trying to get to another filesystem
because the main one is broken.

take a look at the gpart(8) manual, expecially the ATTRIBUTES section. if
you
are running with a GPT scheme you can use the "bootonce" attribute to do
exactly what you asked for.

Thanls, but I need it for MBR.
gpart works with MBR.
