I'm not on the rsync mailing list, but the writer asks if any
mainstream UNIXs support EAs (as opposed to ACLs).
I know that the following do:
VxFS (from Veritas, heavily used in HP-UX and Solarix at a minimum)
AdvFS (From Tru64 (i.e. Compaq/HP))
UFS, NFS (As patched for Tru64 from Compaq/HP)
XFS and CXFS (From SGI's UNIX and their Linux XFS port as well).
So in the top 5 Commercial UNIXes, the only one that may not support
EAs is AIX. (I don't know AIX).
FYI: Tru64 man page:
Unfortunately, I don't know of any kind of compatibility amongst the
above, but I'm no expert.
Also, IIRC ACLs are required for DOD Orange Book qualified secure
Feel free to forward this info to the rsync list.
