Oppinion: Flesh-Out of SFS Article

I've just finished embellishing the SFS article and I want an opinion on how it looks and how it could be improved.

I fixed some incorrect details (SFS can be a partition, names are UTF-8) but otherwise it looks good

Thanks, the spec is a little bit confusing on where the super-block actually is but I presumed it to reside in the MBR because it had space for the partition table. Maybe the spec should be updated to explicitly state the where the super-block should be.

The space for the partition table is there because logical volumes have a partition table too.

If you read the specification correctly, it refers to the 'storage medium' as a general concept to refer to a place to store data. Wether that is the entire disk, or a part of the disk is not mentioned. Attempting to do so would result in incompleteness since one can't possibly know all forms of data storage and their organisation. The only thing that happens is that space is reserved for when specific areas of sector 0 are required.

For comparison, ISO 9660 only describes a filesystem on a CD. When you burn a CD a TOC, lead-in and lead-out are added since they are required by the CD standard. Hence the filesystem does not start at location 0 on disk. The same holds for partitions on harddisks.

None of the other FS specs I have looked at mention that they should start at physical location 0 either, but rather imply the medium to be the location where the FS is located.
