Good proposal. Richard: Add this to mine.
An empty partition should report
/dev/sdb6: data
whereas a recognizable filesystem should tell lots of info, like
/dev/sdb6: Linux rev 1.0 ext4 filesystem data, ...
or
/dev/sdb6: DOS/MBR boot sector, ... FAT ...
A Linux swap partition looks like
/dev/sdb6: Linux/i386 swap file ...

As said: Old school.
Just some filesystem type that is supposed to take large data files.

Using /mnt for custom mount points does not look like a grave mistake,
at least.
Old school is:
http://www.tldp.org/LDP/Linux-Filesystem-Hierarchy/html/mnt.html
"This is a generic mount point under which you mount your filesystems
or devices. [...] This directory usually contains mount points or
sub-directories where you mount your floppy and your CD. You can also
create additional mount-points here if you wish."
About as old as above LFS is:
http://www.pathname.com/fhs/pub/fhs-2.3.html#MNTMOUNTPOINTFORATEMPORARILYMOUNT
"/mnt : Mount point for a temporarily mounted filesystem
Purpose
This directory is provided so that the system administrator may
temporarily mount a filesystem as needed. The content of this directory
is a local issue and should not affect the manner in which any program
is run.
This directory must not be used by installation programs: a suitable
temporary directory not in use by the system must be used instead."
Do we have newer specs ?
Have a nice day :)
