Red Hat's Atomic OS is a read-only filesystem that uses ostree underneath. Installing packages using dnf does not work. Instead use the native package installer 'rpm-ostree install' if an ostree booted filesystem is detected. Utilize various options -y: always install --apply-live: apply changes now instead of waiting for a reboot --idempotent: do not error if package is already installed --allow-inactive: do not error if package is already committed Also include detection of CentOS Stream and leverage the same plugins.

Red Hat's ostree is a read-only filesystem that maps everything under /usr. The only persistent data is mapped under /etc and /var. To support /mnt, ostree mapped the directory under /var/mnt and created it at first-boot using systemd-tmpfiles. The directory /var/mnt does not exist at container creation time and thus restraint-rhts package fails to create /mnt/scratchspace and /mnt/testarea at install time. Switch these directories to systemd-tmpfiles that are created on boot. This resolves the problem and allows the packages to be installed during the container build or anaconda kickstart.

Ostree has bootable containers with a read-only filesystem. This filesystem doesn't support dnf install nor current restraint directory layout and needs a few tweaks. With these changes, restraint should work out of the box with bootable containers over ssh.
