Hello, I try to copy a vm image to a directory like this & "/nfs/share-temp/panbox-rel.img" `File.isCopyOf` panboxName but when I run this, I get this error message sixs3.exp.synchrotron-soleil.fr /root/vm/panbox-rel.img owner picca:grp-instrumentation ... done cp: failed to preserve ownership for '/nfs/share-temp/panbox-rel.img.propellor-new~': Operation not permitted ** error: cp failed ** warning: Cannot continue! CallStack (from HasCallStack): error, called at src/Propellor/Message.hs:143:9 in propellor-5.6.0-GGUJL7KihFnDmzjFSP3dov:Propellor.Message sixs3.exp.synchrotron-soleil.fr /nfs/share-temp/panbox-rel.img is copy of /root/vm/panbox-rel.img ... failed I understand thaht it is not possible to use cp --preserve... on the nfs system. So is seems that Propellor miss a copyFile whcih is usable also on nfs system :). what is the best way to solve this problem. I can copy the file without the preserve flag. Cheers Fred
