### Test log tst_test.c:1888: TINFO: === Testing on vfat === tst_test.c:1217: TINFO: Formatting /dev/loop0 with vfat opts='' extra opts='' mkfs.vfat: Partitions or virtual mappings on device '/dev/loop0', not making filesystem (use -I to override) tst_test.c:1217: TBROK: mkfs.vfat failed with exit code 1
The error message indicates that the loop device contains existing data and mkfs.vfat refuses to overwrite it, which would be part of your test environment.
Can you try adding the suggested '-I' flag to the mkfs.vfat invocation so it overrides the warning?
