Diagnostic Steps

On the matching version RHEL machine switch to a directory with at least 100G of space:
```
 cd _/path/to/large/volume_
```
Download RHEL DVD iso from https://access.redhat.com/downloads/ to your current directory.

Download and install a basic set of packages and their dependencies required for functional use of chroot:

 yumdownloader --resolve --alldeps --downloaddir ./pkgs redhat-release filesystem setup glibc bash coreutils dnf strace
 dnf install strace -y
 time strace -qfTttvys 192 -e trace=read,execve -o ./rpm-strace-minimal-package-set-filtered-read-execve.txt rpm -iv --root `pwd`/fakeroot ./pkgs/*

Obtain a first set of users and groups installed by the basic set of packages:

 grep "read(.*\.rpm>\|execve(.*\(\"/\(usr/sbin\|sbin\)/\(useradd\|adduser\|newusers\|usermod\)\"\|\"/\(usr/sbin\|sbin\)/\(groupadd\|groupmems\|groupmod\)\"\)" ./rpm-strace-minimal-package-set-filtered-read-execve.txt | sed -e "s#^[0-9]\+[ ]\+.*read([0-9]\+<.*/\(.*\.rpm\)>.*#\1#" > ./partial-results-minimal-package-set-grep-read-execve-sed-get-rpm-filename.txt

 uniq ./partial-results-minimal-package-set-grep-read-execve-sed-get-rpm-filename.txt | grep execve -B 1 > ./partial-results-minimal-package-set-uniq-grep-execve-B-1.txt 

 sed -e "s#^[0-9]\+[ ]\+.*execve(\(\"/\(usr/sbin\|sbin\)/\(useradd\|adduser\|newusers\|usermod\)\"\|\"/\(usr/sbin\|sbin\)/\(groupadd\|groupmems\|groupmod\)\"\).* \[\(.*\)\], \[\"[A-Z_]\+.*#\6#" -e "s#[,]##g" ./partial-results-minimal-package-set-uniq-grep-execve-B-1.txt > ./final-results-minimal-package-set.txt

Set up a yum ISO repository:

 cat > ./fakeroot/etc/yum.repos.d/media.repo <<MEDIA.REPO_EOF
 [InstallMedia-BaseOS]
 name=Red Hat Enterprise Linux BaseOS
 mediaid=None
 metadata_expire=-1
 gpgcheck=0
 cost=500
 enabled=1
 baseurl=file:///mnt/rhel_iso/BaseOS/

 [InstallMedia-AppStream]
 name=Red Hat Enterprise Linux AppStream
 mediaid=None
 metadata_expire=-1
 gpgcheck=0
 cost=500
 enabled=1
 baseurl=file:///mnt/rhel_iso/AppStream/
 MEDIA.REPO_EOF
 
 chmod 644 ./fakeroot/etc/yum.repos.d/media.repo; \

 mkdir -p ./fakeroot/mnt/rhel_iso

Get into chroot and mount the ISO:

Download chroot-fakeroot.sh and make it executable:

  chmod +x ./chroot-fakeroot.sh

On RHEL 8:

  mv ./RHEL-8.7.0-20221013.1-x86_64-dvd1.iso ./fakeroot/root/
  ./chroot-fakeroot.sh -r ./fakeroot/
  mount -o loop ~/RHEL-8.7.0-20221013.1-x86_64-dvd1.iso /mnt/rhel_iso/
  cd

On RHEL 9:

  mv ./RHEL-9.1.0-20221027.3-x86_64-dvd1.iso ./fakeroot/root/
 ./chroot-fakeroot.sh -r ./fakeroot/
  mount -o loop ~/RHEL-9.1.0-20221027.3-x86_64-dvd1.iso /mnt/rhel_iso/
  cd

Install all packages under chroot:

 dnf -y module enable \*

 time strace -qfTttvys 192 -e trace=read,execve -o yum-strace-filtered-read-execve.txt dnf -y --skip-broken install \*

 grep "read(.*\.rpm>\|execve(.*\(\"/\(usr/sbin\|sbin\)/\(useradd\|adduser\|newusers\|usermod\)\"\|\"/\(usr/sbin\|sbin\)/\(groupadd\|groupmems\|groupmod\)\"\)" yum-strace-filtered-read-execve.txt | sed -e "s#^[0-9]\+[ ]\+.*read([0-9]\+<.*/\(.*\.rpm\)>.*#\1#" > partial-results-grep-read-execve-sed-get-rpm-filename.txt

 uniq partial-results-grep-read-execve-sed-get-rpm-filename.txt | grep execve -B 1 > partial-results-uniq-grep-execve-B-1.txt

 sed -e "s#^[0-9]\+[ ]\+.*execve(\(\"/\(usr/sbin\|sbin\)/\(useradd\|adduser\|newusers\|usermod\)\"\|\"/\(usr/sbin\|sbin\)/\(groupadd\|groupmems\|groupmod\)\"\).* \[\(.*\)\], \[\"[A-Z_]\+.*#\6#" -e "s#[,]##g" partial-results-uniq-grep-execve-B-1.txt > final-results.txt

 exit

Combine the users and groups added while creating the chroot environment and those installed while running under chroot, as well as adding results for conflicting packages:

On RHEL 8:

  cat ./final-results-minimal-package-set.txt > ./full-final-results.txt

  cat ./fakeroot/root/final-results.txt >> ./full-final-results.txt

  cat >> ./full-final-results.txt <<CONFLICTS_OR_MISSING_RHEL8_EOF

Parse the results:

Download parse-results.sh and make it executable:

   chmod +x ./parse-results.sh

On RHEL 8:

   cat full-final-results.txt | ./parse-results.sh > current-results-RHEL-8.7.iso.txt

On RHEL 9:

   cat full-final-results.txt | ./parse-results.sh > current-results-RHEL-9.1.iso.txt
