After a fresh install of Kinoite 43 on a Surface Pro 6, I updated then attempted to follow the current installation instructions for Fedora SilverBlue. The rpm-ostree override command fails when running the posttrans script with the following error:
error: Running %posttrans for kernel-surface-core: bwrap(/bin/sh): Child process killed by signal 1; run journalctl -t 'rpm-ostree(kernel-surface-core.posttrans)' for more information

Thinking that this may be an issue with the size of the EFI partition as some previous issues suggested, I increased the EFI partition to 4 GB and reinstalled. The issue still occurred.
