I figured as much after digging through the SLES-patched cp, I just hadn't gotten as far as grabbing the libattr source and seeing what that was. Is this blacklist specific to the SLES libattr, or is this in the released version? > A blacklist somewhere in /etc would be even better though I guess. Definitely, yes. Given that libselinx gropes around in a several files already, adding one more won't hurt. Something like /etc/libattr.conf? > > It would probably be preferrable that cp only copy EAs that it understands. > > What to do with unknown attributes? Warn? Err out? Warn once, maybe with pointer to /etc/libattr.conf for adding to include or exclude list. Given that copying file attributes isn't guaranteed in any case, we can probably safely live without copying everything.
