What were you trying to do that didn't work?

When building https://gitlab.com/redhat/rhel/containers/ubi9/, the package installation produces errors because the subscription-manager %post script attempts to use "find" and "xargs" before they're installed.

What is the impact of this issue to you?

The error is logged in a message which includes the name of the temporary file used to hold the scriptlet, and that gets stored in the history database and baked into the image, interfering with reproducibility.

Please provide the package NVR for which the bug is seen:

subscription-manager-1.29.46-1.el9

How reproducible is this bug?:

Highly

Steps to reproduce

1. git clone git@gitlab.com:redhat/rhel/containers/ubi9.git
2. mkdir ubi9/prefetched
3. curl -o ubi9/prefetched/2022-IT-Root-CA.pem https://certs.corp.redhat.com/certs/2022-IT-Root-CA.pem
4. cd ubi9; git checkout rhel-9.7.0
5. podman build -t dir:/tmp/build1o -v `pwd`/prefetched:/prefetched:ro,z .
6. cd /tmp/build1o
7. d=`jq -r '.layers[0].digest' manifest.json`; tar xvf ./${d##*:}
8. sqlite3 ./var/lib/dnf/history.sqlite ".dump console_output"

Expected results

No "command not found" errors from randomly-named scripts.

Actual results

...

INSERT INTO console_output VALUES(7,2,1,'/var/tmp/rpm-tmp.hMXkSP: line 17: find: command not found');
INSERT INTO console_output VALUES(8,2,1,'/var/tmp/rpm-tmp.hMXkSP: line 17: xargs: command not found');
