On further consideration, there are other places where things could be happening, before the "system" is fully started, meaning before the 'mount' options you're using would have any effect. These don't necessarily do anything (in the "write" sense ;), but are places to consider checking: BIOS, grub/lilo/other boot loader, kernel and kernel options for startup, initrd.
The BIOS should be completely fs-agnostic, but yes, actually, the first stage of the boot loader most certainly doesn't care about the fstab, and if it's a good boy, then it *might* increment the count.
After that, the fstab should be taken into account, but maybe the mount count still isn't covered by the ro option. Wild guess: if it's not the mount command, then.. fsck?
Better start digging some facts.
These days, you need to know udev and udev rules files format (which I don't), to figure out where and how to set this up. Perhaps someone else on the list would have some ideas for you on how to do this?
http://reactivated.net/writing_udev_rules.htmlThis is a good reference, although maybe a bit outdated considered the recent developments. Shouldn't be anything significant if at all, and definitely enough for that.
