Anything else?

silverblue uses osstree to generate immutable filesystem of the OS level file tree. for example /usr.
But /var/log isn't and if created manually /var/log/bareos/bareos-filedaemon-install.log and tested various rights. (including disabling selinux).
the new installed Programms using rpm-ostree install are available after a reboot by design. I think the filesystem looks different to the preinstall script that fails.
The rpm package for fedora 41 worked with Silverblue.
