Fedora-19
misses tar at minimal setup
[snip]
for some reason fedora-18/19 got tar out of base system, so we are
forced to find some solution, although manual configuration is required
anyway (repository, networking etc...).
there was attempt to use python tar module, however this module has a
bug when last block is empty, so it is not suitable for usage.
cpio is alternative for fedora, however it is rightfully missing from
other distributions as it is much less used. as we do not support hosts
using different distributions, we are ok now.
in future, we can use python self extract script, work already performed
at: I1e5ddab9ae87979da7d7296c4f3c7ef08e21e903 at the price of
complexity.

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,
As far as I know most distributions use initramfs to boot, and that
requires the cpio command to build it, so all machines running Fedora,
RHEL, CentOS, Debian, Ubuntu and Gentoo (if using genkernel) should have
cpio installed even for minimal installations.
Hi,
Binary based distributions do not build initramfs on the fly, right? Require
cpio to build initramfs is like require gcc to build kernel, no?
Fedora, RHEL, CentOS, Debian and Ubuntu (for example) do build initramfs
on the fly when the kernel is installed/updated, and that uses the cpio
command. So any updatable installation has it.
RHEL, CentOS does have tar at minimal as far as I know...
Gentoo does not have genkernel/cpio in stage3 (minimal).
It doesn't have any kernel either, so you need to build it (according to
the installations instructions) which would need to build the initramfs
as well, and that (if using genkernel, at least) requires cpio.
All but Fedora have tar at minimal.
Regards,
Alon
