Older and simpler filesystems used to combine the naming with the space 
allocation.  CP/M, and (IIRC) the GE/Honeywell mainframe systems I used to 
work with.  MS-DOS FAT filesystems might have supported multi-names but 
refused to administer them before long filenames were implemented as special 
cases.  I first ran into multi-names on Multics, where the Volume Table of 
Contents controlled disk space allocation and directories provided name-
keyed access to the VTOC entries.  Pretty much as Linux does now with 
directories and inodes.
