The point is not on using symlinks, I do this for test.
As you suggest (in the install section) to setup files in
multi-user.target.wants, I tested too, but it changes nothing.

I've tested deleting fstab file and this change nothing to my previous
test with a blank fstab. Root filesystem is still ro and no options
are took.

Last test was done on systemd 197 on ArchLinux.
