Proof of concept for Amazon Linux 2 conversions

[bocekm]

Steps to get the AL2 converted:

yum-config-manager --add-repo https://copr.fedorainfracloud.org/coprs/g/oamg/convert2rhel/repo/epel-7/group_oamg-convert2rhel-epel-7.repo
yum install -y convert2rhel*1455*
yum install -y https://cdn-ubi.redhat.com/content/public/ubi/dist/ubi/server/7/7Server/x86_64/os/Packages/p/python-dmidecode-3.12.2-4.el7.x86_64.rpm  # The python-dmidecode version in AL2 repos is older than the RHEL 7 sub-man requires
cat >/etc/convert2rhel.ini <<EOF
[inhibitor_overrides]
allow_unavailable_kmods=true
skip_kernel_currency_check=true
[subscription_manager]
EOF
read -sp "RHSM organization: " org && echo "org = $org" >> /etc/convert2rhel.ini
read -sp "RHSM activation key: " key && echo "activation_key = $key" >> /etc/convert2rhel.ini
convert2rhel -y --debug

What might be causing issues during or after the conversion:

• kernel 4.14.355 or 5.10.234 (vs 3.10.0 on RHEL 7)
  • AL2 is offered with two different kernel major versions
• glibc 2.26 (vs 2.17 on RHEL 7)

Especially when it comes to kernel drivers.
