Summary: mount applet not consistent with real state
Description:
Hi,

it happens that the mount applet claims to have unmounted the CF card when
in fact the CF card is still mounted (as verified by the mount command from
the console). This can lead to MAJOR data loss (it did for me, see my rant
at http://bugs.openembedded.org/show_bug.cgi?id=944)

Regards

Rolf

Actually, it seems that (with the Familiar images I have tested with at
least) neither the old cardmon applet nor the pcmcia applet make any
attempt to unmount cards before doing a software eject, and the eject will
happily go through leaving the card mounted.

Now, I have no idea if any of this is system related, and I have yet to
even determine a way of programmatically finding the link between a PC card
slot and a mounted block device, but this clearly needs to be fixed.

Thanks Paul, for taking this up.

I have done some more investigation into this. I found a bug in the PCMCIA
scripts being used in Familiar 0.8.4 which resulted in unmount errors not
being sent back to cardmgr. However, when I fixed that bug it still allowed
the card to be removed with "cardctl eject". Perhaps that is expected
behaviour, I don't know.

I'd love to be able to test this on a device with PCMCIA slots using
up-to-date software, but unfortunately none of my iPAQs that have PCMCIA
slots can run 2.6 at the moment. Perhaps I will try it on my laptop.
