Remount an already-mounted filesystem without unmounting it

Necessary for fsck for example.

The remount functionality follows the standard way how the mount command works with options from fstab. It means the mount command doesn't read fstab (or mtab) only when a device and dir are fully specified. After this call all old mount options are replaced and arbitrary stuff from fstab is ignored, except the loop= option which is internally generated and maintained by the mount command.

It does not change device or mount point.

Know a better way?

If you can do better, submit your command here.

What others think

"stuff from fstab is hardly 'arbitrary'
