I had a program, actually a set of programs, which test a file-system.
And this set of programs needed such a feature quite a lot, to sync the
FS which is being tested and nothing else - for both performance reasons
and to put more stress to the FS under testing. We used -o remount, rw
for this - but this forced us to run under root.
IOW, there are programs which take a mount point as an input parameter
and want do things with the whole FS, not only individual files.
