It may, but that is RHEL, and this Fedora, no ? > What is the likelihood of > those users actively upgrading anyway? Upgrades in RHEL are a much bigger deal, and usually better researched (also rare, usually people reinstall there). In Fedora distro-upgrading w/o looking too hard at release notes is common. Of course the amount of people that uses TPM 1.2 in Fedora is probably very small, so this change may be ok, but I just wanted to raise the issue. Is there a way, after update to still use TPM 1.2 at all (even if it requires installing copr/other repo packages)? Or will people need to roll back their system to access those secrets at all ?
