That's the problem.  Due to this, the info for the partition isn't
printed at all.

That's not the same thing.  This information *would* be available, but
it's only fetched if the partition info could be fetched.  What's
actually missing is access to the partitions and their size, not access
to the mount points to partitions.  That's why you only see sda and sdb,
but not any one of the partitions.  I don't see how to print
/proc/partitions correctly without this info.
