My guess, and it is a guess (though potentially comparing against the
original debian initscripts we started with, or looking through git
history, may be informative) is that the original default value of
rootcheck was yes, and hence the conditional in the loop setting
rootcheck=no made sense, but it was changed at some point in the
history due to the use of non-checkable filesystems.

If we change the default back, we'll break everyone using the stock
fstab or one based on it, as the default sets pass=1 for the 'rootfs'
mount. One option would be to source /etc/default/rcS after the
definition of the defaults prior to the loop, thereby allowing a per
machine rcS which changes the default value.
