Upstream commit: 6091f3f Adds support for the --transient option on all transactions. Passing --transient on a bootc system will call `bootc usr-overlay` to create a transient writeable /usr and continue the transaction. Specifying --transient on a non-bootc system will throw an error; we don't want to mislead users to thinking this feature works on non-bootc systems. If --transient is not specified and the bootc system is in a locked state, the operation will be aborted and a message will be printed suggesting to try again with --transient. Resolves: https://issues.redhat.com/browse/RHEL-70917
Upstream commit: 80a62d8 Documents the new `--transient` command-line argument and `persistence` configuration option. I tried to use a table for listing the valid options for `persistence`, but RST does not automatically wrap table cells containing long lines, so a list was much easier. Resolves: https://issues.redhat.com/browse/RHEL-70917
Upstream commit: f3abee5 Using libostree gives us more detail about the current state of the deployment than only checking whether /usr is writable. Resolves: https://issues.redhat.com/browse/RHEL-70917
Upstream commit: fa47a25 To keep /usr read-only after DNF is finished with a transient transaction, we call `ostree admin unlock --transient` to mount the /usr overlay as read-only by default. Then, we create a private mount namespace for DNF and its child processes and remount the /usr overlayfs as read/write in the private mountns. os.unshare is unfortunately only available in Python >= 3.12, so we have to call libc.unshare via Python ctypes here and hardcode the CLONE_NEWNS flag that we need to pass. Resolves: https://issues.redhat.com/browse/RHEL-70917
Upstream commit: 76a0c33 dnf-bootc's only job is to Require python3-gobject-base, ostree, ostree-libs, and util-linux-core, which are needed to interact with bootc systems. We don't want to add these dependencies on `python3-dnf` because we don't want them on non-bootc systems, so we use a subpackage. Resolves: https://issues.redhat.com/browse/RHEL-70917
Upstream commit: 5a4f6c4 This backport actually uses RHEL-9 libdnf version. Resolves: https://issues.redhat.com/browse/RHEL-70917
