But even better if you turned guestfs_feature_available into a non_daemon_function, added a new guestfs_internal_feature_available daemon_function, and then cached the results on the library side. They can never change for the duration of a libgu...

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

The existing mechanism was clunky, slow and used ~ 10 MB of local disk. Rich.
