  It means that the 1.1 kernel is checking the "file system clean" status
bit in the file system, and find that the file system was not marked clean.
The 1.0 fsck doesn't know anything about the clean status, and can not
set the file system clean.  You need to build (or otherwise obtain) a
newer fsck.

  There are a number of other differences between 1.0 and 1.1 - one
serious difference is in the ados filesystem:  the read-only status
is now enforced and thus it must be mounted read-only.  The 1.0
mount_ados does not have the abilitity to do a read-only mount, and
will fail on a 1.1 kernel.

  The 1.1 release will include an upgrade procedure, which will copy
the new distribution files to an existing system.

  I've mounted amigados partitons on read-only file systems with no
problem.  You wouldn't be able to copy the new kernel to /netbsd though.
And until you update mount_ados, you won't be able to mount any ados
partitions anyway.
