anaconda kickstart generated by the installer
Comment 3 Sandro Bonazzola 2023-08-04 09:35:46 UTC 
# guestfish --rw -i -a centos-stream9.qcow2 ls /etc/os-release
libguestfs: error: ls0: opendir: /etc/os-release: Not a directory

so yes, the os-release file is missing. Perhaps it's more like an anaconda bug
Comment 4 Sandro Bonazzola 2023-08-04 09:41:07 UTC 
weird, 
# guestfish --rw -i -a centos-stream9.qcow2 sh "ls /etc/os-release"
/etc/os-release

# guestfish --rw -i -a centos-stream9.qcow2 sh "cat /etc/os-release"

so it's there. No clue on why it's not being found at boot.
