--- Comment #9 from Cheng Cui <cc@FreeBSD.org> ---
(In reply to Warner Losh from comment #8)

> It breaks / and /usr being on different partitions.

Please let me know if these are the partitions in default. Because as an
average user who simply follows the bandbook and finds installation images =
from
a well-known place like https://www.freebsd.org/where/, does not and shall =
not
care about advanced details about where the "/rescue" is.

> Why don't you have /rescue?

After I re-installed my box again with FreeBSD 14.0-RELEASE through pxeboot=
 and
by using the content from the FreeBSD-14.0-RELEASE-amd64-disc1.iso, I found
there shall be clarification that the execute of "rc.initdiskless" is part =
of
the booting process, not a start of the installation process. So I encounte=
red
the "/rescue/tar: not found" again, but with the change I could finish the =
boot
and then start the installation. Once the installation finished, I found the
files in "/rescue". This means although there are no files in "/rescue" from
the ISO, they will be generated during the installation. Then, the system h=
as
the "/rescue".

So far, the only place that the keyword "rescue" shows up in "rc.initdiskle=
ss"
is where the "/rescue/tar" shall be replaced with "/usr/bin/tar" in the
proposed patch. Given "rc.initdiskless" is used during the pxeboot, and fil=
es
in "/rescue" are not ready yet and will be ready after the installation, I
think the change is not bad.

Also please let me know if the revert of commit
https://cgit.freebsd.org/src/commit/?id=3D6e352319b6ff97a20b53d13a6df76b71d=
d12afc9
is a better solution, although I don't think so.
