In my quest to migrate work systems from Ubuntu to Debian, I began testing the imaging system. The imaging is basically two partitions on a workstation and two shell-scripts. The two partitions are /boot and the system (/) partition.
The prep script kept failing when copying the /boot partition. Each time the script attempted to run
fsck the command would fail with related super block messages.
I was testing the imaging process on Slackware 14.2. The /boot partition size is configured to 250 MB. This has worked fine through many images. Eventually I found that changing the new partition size to 256 MB resolved the problem.
Updating my local testing system to 256 MB was straightforward, but why the failure?
I don’t know. Yet Another Shoulder Shrug moment.
