If I could have done so, I would have re-opened this bug: http://bugs.gentoo.org/show_bug.cgi?id=151257. The patch suggested there does not resolve the problem of white spaces in mount points in my opinion. De-mangling of the mount points must be done *before* the strcmp(), not afterwards. Additionally, I would suggest testing for "\0nn" when looking for an octal number rather than testing for "\nnn".
