It's probably better to silently ignore this case instead of crashing. Rich. --

Sounds reasonable; attached a patch for it. -- Pino Toscano

This version shouldn't be ever called, since it is called when optgroup_linuxxattrs_available returns true, which is not the case in the !HAVE_LINUX_XATTRS block (where the abort version of copy_xattrs is implemented). -- Pino Toscano

Hi, attached there is a prototype of patch for adding a new copy-attributes command. Such command would allow copy the attributes of a "file" to another, so for example in guestfish: copy-attributes foo bar permissions:true xattributes:false would only copy the permissions of foo to bar, not copying its extended attributes too. Just few notes: - my first daemon command, so

This is a PoC patch for NFSv4/ZFS ACLs. The objective of the patch is that rsync --acls support NFSv4/ZFS ACLs without requiring a new command line option NFSv4 ACLs can't be represented using POSIX draft ACLs, if an NFSv4 ACL is present a separate POSIX draft ACL will not be present and there are new APIs to access NFSv4 ACLs. So we need to distinguish between NFSv4 ACLs and POSIX ACLs in
