again (cmp.
IMHO, it should be
"owner/group concept and permissions" (there are even extensions for ACLs) and
"linking" is a part of a build process (typically after compiling), so maybe "support for hard/soft links" is a better expression

And what about
- other "special files" like named pipe files, device files,...
- file name conventions (Which are the file name restrictions in FAT?)
