Re: MBR partition table and the "active" flag

Hi,

not *entirely* related, but possibly relevant.

Per default, U-Boot seems to check for the flag at last on some
targets.  I ran into that a few days ago on the Pinebook.  The U-Boot
in question was built from FreeBSD's ports system and I don't see any
local changes that might have caused this, so I suspect this is the
default behavior.  At least when booting Linux, U-Boot scans for
certain files (e.g., "/boot.scr") on all bootable partitions and loads
the first it finds.

On NetBSD, U-Boot might do something different.  I've been wanting to
look at that anyway, I can tell you then if the flag is relevant
to us.
