I have an error (about symlinks it seems) that i have never met in years:
Cannot change mode.
Apart from this message (and return code != 0), the ’tar extract’ is ok.

/tmp is under ntfs filesystem, all packages are up to date (e.g. /bin/tar
--version is 1.34).
I recently got this during a package update build, when it decided to tar a
build directory, which contained only symlinks to files in the src directory,
which the tar did not include, which would have created many dangling symlinks.
I fixed the issue by adding -h, --dereference to give chf and tar real files.
