Not only do they look the same at user level, but directories are
implemented as lists of (name, inum) pairs which are ordinary files
with a special attribute bit, metadata is stored in `inodes', inodes
have pointers to data blocks, an indirect block, and some doubly
indirect blocks, and a triply indirect block, etc.  The disk is
statically partitioned into inodes and data blocks.

MS-DOS, VMS, CP/M, NT, and ITS do things *very* differently.

Much more the same than, say, VMS's multitasking design, or NT's, is the
same as Linux.
