I just tried to use arm-image-installer to build an Rpi4 IoT image using the Fedora-39 IoT release image: Fedora-IoT-39.20231103.1-20231103.1.aarch64.raw.xz

I asked the installer to resize the partition.

At the end of the run, I get:

The partition table has been altered. Calling ioctl() to re-read partition table. Syncing disks. e2fsck 1.46.5 (30-Dec-2021) /dev/sdb3 has unsupported feature(s): FEATURE_C12 e2fsck: Get a newer version of e2fsck!

root: ********** WARNING: Filesystem still has errors **********

resize2fs 1.46.5 (30-Dec-2021) Please run 'e2fsck -f /dev/sdb3' first.

I'm guessing the file system was created with a newer version of e2fsprogs than that supported in F38 (and there is no update on F38) and it created a new default feature in the filesystem, which isn't supported in the older version. According to google, this might be the orphan_file feature, but I have not verified that.
