yes the test got bogus by kernel upstream adding more info to
/proc/mounts. although current version in debian is fine too.

hmmm don't see that as improvement, debians version seems more readble.
if you have futher enhancements to it please base the patches on it.

the only trouble on the debian side would be another mount option
beginning with ro, but that didn't get reported yet nor do i know one.

thanks.
