# (set -x; umount /mnt/tmp; \rm -f ext4.img; truncate -s 2M ext4.img && mke2fs -q -t ext4 ext4.img && mount -o usrquota ext4.img /mnt/tmp && quotacheck -cu /mnt/tmp && repquota /mnt/tmp && umount /mnt/tmp && e2fsck ext4.img && tune2fs -O quota -Q usrquota ext4.img && mount -o usrquota ext4.img /mnt/tmp && repquota /mnt/tmp)
+ umount /mnt/tmp
umount: /mnt/tmp: not mounted.

+ mount -o usrquota ext4.img /mnt/tmp
+ quotacheck -cu /mnt/tmp
quotacheck: Your kernel probably supports ext4 quota feature but you are using external quota files. Please switch your filesystem to use ext4 quota feature as external quota files on ext4 are deprecated. You can enable the feature by unmounting the file system and running 'tune2fs -O quota <device>'.
