Subject: [PATCH] squish: BLS: only write /etc/kernel/cmdline if writable
On OSTree systems, `grub2-mkconfig` is run with `/etc` mounted read-only
because as part of the promise of transactional updates, we want to make
sure that we're not modifying the current deployment's state (`/etc` or
`/var`).
This conflicts with 0837dcdf1 ("BLS: create /etc/kernel/cmdline during
mkconfig") which wants to write to `/etc/kernel/cmdline`. I'm not
exactly sure on the background there, but based on the comment I think
the intent is to fulfill grubby's expectation that the file exists.
However, in systems like Silverblue, kernel arguments are managed by the
rpm-ostree stack and grubby is not shipped at all.
Adjust the script slightly so that we only write `/etc/kernel/cmdline`
if the parent directory is writable.
In the future, we're hoping to simplify things further on rpm-ostree
systems by not running `grub2-mkconfig` at all since libostree already
directly writes BLS entries. Doing that would also have avoided this,
but ratcheting it into existing systems needs more careful thought.
