Maybe AmigaOS/fsck doesn't touch the clean flag at all ... ?
(If you use it on a clean filesystem, the filesystem stays clean and
NetBSD does not check it again.)

However, there is one big difference between both fsck versions:
AmigaOS/fsck can only be used if the filesystem is mounted, while
NetBSD/fsck can only be used if the filesystem is not mounted (or mounted
read-only in the case of '/'). So there may be a "conceptional difference"
concerning the handling of the clean flag.

On the other hand the AmigaOS/fsck from the BFFS 1.5beta was derived from
NetBSD sources sometime in 1994. Does anybody know whether there have been
changes to the NetBSD filesystem since then, that may perhaps cause
incompatibilities?
