Review comments at @src/grubconfigs.rs:
- Around line 179-201: Update ensure_grub_permissions to validate that grub.cfg
resolves only to the documented /boot/loader/grub.cfg target before changing
permissions, and apply the mode through the validated opened target rather than
following an unchecked path. Narrow the symlink test to accept only that target.

We have cases where `grub2/grub.cfg -> ../loader/grub.cfg` and since we moved to cap-std APIs, the metadata gathering for the file fails since the target leads to outside the filesystem (which is the directory `grub2` in this case). To fix, use `std::fs` APIs to get metadata Use `GRUBCONFIG_FILE_MODE` constant instead of raw 0600 mode Signed-off-by: Pragyan Poudyal <pragyanpoudyal41999@gmail.com>
bootc 1.16.14 (in copr) uses composefs.digest= cmdline, but since we don't rebuild the initramfs, we never include that digest as a condition for bootc-initramfs-setup to run which fails the VM startup Disable C10S tests for composefs, for now Signed-off-by: Pragyan Poudyal <pragyanpoudyal41999@gmail.com>
