Use the 'mount' command instead of /proc/mounts to get a list of matching
filesystems.
This because /proc/mounts reports a pool with a space 'rpool 1' as
'rpool\0401'. The space is encoded as 3-digit octal which is legal.
However 'printf "%b"', which we use to filter out other illegal
characters (such as slash, space etc) can't properly interpret this
because it expects 4-digit octal. We get a instead of the space
we expected. The correct value should have been 'rpool\00401' (note
the additional leading zero).
So use 'mount', which interprets all backslash-escapes correctly,
instead.
