Grow the root partition
The one feature that the setup wizard is missing compared to what I wrote in reform-system-image!43 is growing the root partition. After growing the partition, resize2fs
also works on mounted filesystems. Essentially, you'd run:
parted -s $rootdev resizepart $rootpart_nr 100%
udevadm settle
partprobe $rootdev
resize2fs -p $rootpart
