Got several replies saying more or less the same thing ...

No, but it remounts the disk read-write after it mounts it read-only.
It can switch from ext2 to ext3 at that point.

That works, but I don't see why I should have to specify additional
commandline options.

Can't - it refuses to touch the disk it's standing on even in single user.
This makes it extremely difficult to revert.

And in answer to some other questions:

This machine can't boot off CD, so rescue disks are not an option.
It's remote anyway, and I shouldn't have to screw around with it to do this.
I'm not using initrd

The point remains, if I say I want ext2, I should get ext2, not whatever 
some random developer decides he thinks I should have. Worst of all,
the system then lies to you and says it's mounted ext2 when it's not.
