Comment 18 for bug 885027

Problems with pmount:

1) It does not work out of the box on all distros (it needs configuration)
2) It may not even be installed on some distros, for example, it isn't
installed by default on gentoo.
3) It has been deprecated in favor of udisks (which incidentally calibre tries
to use before falling back to the mount helper)

So, no, pmount is not a suitable replacement.

Fix committed for the latest exploit. Feel free to re-open if you find another
exploit based on 4.
