Unfortunately, the terminology used to discuss Linux filesystem concepts is a bit confusing for newcomers. The terms filesystem and file system are used interchangeably in the Linux documentation to refer to several different but related concepts. They refer to the data structures as well as the methods that manage the files within the partitions, in addition to specific instances of a disk partition.
To further confuse the uninitiated, these terms are also used to refer to the overall organization of files in a system: the directory tree. Then again, they can refer to each of the subdirectories within the directory tree, as in the /home filesystem. Some hold that these directories and subdirectories cannot truly be called a filesystem unless they each reside on their own disk partition. Nevertheless, others do refer to them as filesystems, contributing to the confusion.
Linux veterans understand, from context, the sense in which these terms are used. Newcomers, however, have an understandably harder time discerning the context.
Dakle obe forme: file system i filesystem mogu da se koriste za opisivanje strukture i načina za čuvanje podataka i za opis organizacije fajlova unutar sistema t.j. hijerarhiju (stablo) direktorijuma, a značenje zavisi od konteksta u kom je izraz upotrebljen. Zato sam predložio da se naglasi razlika, posebno ako se wiki stranica proširi do govori o obe teme.
