Fortunately, other libraries are starting to allow transparent use!

Jannik Glückert recently implemented support in libstdc++ [0][1] which will arrive in GCC 14.

[0] gcc.gnu.org/git/?p=gcc.git;a=c
[1] gcc.gnu.org/git/?p=gcc.git;a=c

glib will do the same in >=2.78 thanks to gitlab.gnome.org/GNOME/glib/-/.

EDIT: I forgot to mention, KDE's kio handles it too. So, together, the respective KDE and GNOME file managers and such should be fine.

And last but in no way least, GNU coreutils 9.0 defaults to --reflink=auto for cp and install.

Let me know if there's other software out there which supports this transparently.

Reflinks aren't particularly new, and nor is copy_file_range or even sendfile (see the GCC commits), but it's interesting how often these improvements are sittong on the table waiting for someone to claim them.

Check the guts of your favourite libraries, you might be surprised!

Bonus: I should say, zfs doesn't yet support this in a release on Linux, surprisingly.

Support was recently added on master in github.com/openzfs/zfs/pull/13 but only for FreeBSD. I believe Linux support is in the works.

Bonus2: Portage >=3.0.48 won't overwrite identical files on the target filesystem as well: bugs.gentoo.org/722270. Thanks to Michael Egger for the contribution!
