my man page says extended xfs attributes can have 256-byte names
with up to 64K of data.
Is there a limit on the number of extended attributes max data size or
name size?
I.e. could I have 1000 attributes with 64K of data each?
Is there a strong reason why the file and data sizes were limited to
256/64K?
Would they be hard to 'generalize' to max-path-segment-len/max-filelen?
Only reason I wonder is wondering what file systems besides apple's
"HPFS"(?) and
MS's NTFS, that allow alternate data-streams of arbitrary length. I'm
not sure about
the maximums on HPFS and NTFS, but I haven't _read_ of any notable
limits (I'm sure
there are some, but it _seems_ you can store alternate file versions in
different data-streams
on NTFS, for example... I.e. could use it as a revision system,
theoretically -- to save
older versions of the file with the right software -- but with XFS, it
wouldn't be so
general case with a 64K data limit -- wouldn't be a show-stopper if one
could 'link'
multiple data-segments, but am just curious about the limitations (not
that I'm planning
on implementing a version control system using data-forks...it was just
an example! :-)).
