Subjectremounting on different directory
Date

Currently,
mount("/dev/hda1", "/mnt/cutie", "adfs", MS_MGC_VAL | MS_REMOUNT, NULL);

returns EINVAL since my /dev/hda1 is mounted on /mnt/robbie. Is there
a good reason why I shouldn't attempt to play with mount to persuade it
to move /dev/hda1 from /mnt/robbie to /mnt/cutie?

My motivation: There are a lot of people who'd like to try ARMLinux
but are put off by having to repartition their hard discs. Rather than
bolt a pseudo-unix filesystem on top of Acorn's ADFS, like UMSDOS does,
I think it would be better to create a large file under ADFS which can
then be mounted via the loopback device. But once you run through the
initrd process, you'll end up with /dev/hda1 mounted on /initrd/adfs and
not be able to free the initrd memory. You can't unmount /initrd/adfs
since the loopback device is on it. All I want to do is move it to
/adfs and then I can get rid of the /initrd.

So does anyone have either a better way of solving this, or objections
to this extension of the mount functionality?
