Yes, Christoph is correct we did implement long file name support long
ago in OS/2.

OS/2 long filenames for FAT were stored as the .LONGFILE extended
attribute.  With
extended attribute emulation on vfat a similar approach could be used, =
although
presumably with different ondisk format for "EA DATA. SF" system file (=
which
stores extended attributes).   If anyone is interested in more detail o=
n this
(probably would be boring to most), we can explain the details.
