            Bug ID: 256395
           Summary: Kernel waits 30 seconds for CD drive before mounting
                    root filesystem
           Product: Base System
           Version: 13.0-RELEASE
          Hardware: amd64
                OS: Any
            Status: New
          Severity: Affects Some People
          Priority: ---
         Component: kern
          Assignee: bugs@FreeBSD.org
          Reporter: miner.ben07@gmail.com

I dual-boot Fedora Silverblue (which I'm using for this bug report) and
FreeBSD. When booting FreeBSD in verbose mode and with boot_mute off, I can=
 see
that the kernel waits 30 seconds from getting ready to mount the root
filesystem and actually doing it. In this time, it repeatedly prints out th=
is
message, once every second:

Root mount waiting for: usbus1
Root mount waiting for: usbus1
...and so on...

If I put a CD or DVD in my laptop's DVD drive, or a USB in one of the ports,
this does not happen, which means it can't be one of the ports specifically=
, or
whatever usbus1 is changes.

I have very little FreeBSD experience, but have used Linux for nearly a year
and as far as I can tell, Linux avoids waiting for a root filesystem on a U=
SB
or CD by making GrUB specify the root device in the command line.

Is there a way to specify the root device in loader.conf or something or is
this a bug without a workaround?
