rd_open_hook() and floppy booting

["Matthew E. Patton" <pattonme_(_at_)_gnpr_(_dot_)_pae_(_dot_)_osd_(_dot_)_mil>]

Can anyone tell me why rd_open_hook() in
/usr/src/sys/arch/i386/i386/rd_root.c has these lines in it?

       if (unit == 0) {
               /* The root ramdisk only works single-user. */
               boothowto |= RB_SINGLE;
       }

I'm quite perplexed as to the assertion made in the comment. I have a fully
configured firewall running multi-user with sshd and other stuff from a
single floppy boot. All I had to do was yank the offending code above.

I can understand if when creating installation diskettes we want the kernel
to stop at single-user mode and run the various scripts. But to force that
behavior here is not the way to do it. (if that is indeed why it's here)
