Quoting Ted Ts'o from
<http://bugs.debian.org/cgi-bin/bugreport.cgi?msg=9;bug=616317>:

| Debian simply doesn't support the mount options for the root file
| system in /etc/fstab having any effect on how the root file system is
| mounted.  The root file system is mounted by the kernel, and the mount
| options used by the kernel are specified by the rootflags= option on
| the kernel's boot command line.

See the remainder of the bugreport for a discussion on how to possibly
remedy that in Debian. As for now, you need to go for kernel command
line options passed by your bootloader.

Cheers,
Flo
