FWIW:

I personally find it least ugly to choose neither cpio nor pyar, and
require installing tar.

Besides Ohad's case in the bug, do we know about real problems?
Is there a specific requirement to be able to run a node on a minimal
installation of $distro? Some other real complications this might cause?

Anyway, if we do have to choose, I'd go with pyar and not cpio. cpio is
used by rpm and initramfs, but other than that it's not very common (? IMHO),
and if we go with it we might face ourselves in the same situation at some
later point in time - that cpio will not be included in a minimal installation
of $distro.

Best regards,
