Public bug reported:
Below is the script we're running. tune2fs doesn't set UUID (can be
checked with blkid) and exits abnormally (so that commands after tune2fs
call are not getting executed).
If we move tune2fs call above the mount command, everything works fine.
Also, it works fine everywhere else including Ubuntu 16.04.3.
#!/bin/bash
set -e
FOREMAN_SIZE=100
UUID="7b48ec41-a9fc-4937-b368-dfeae01c49f7"
MNT=$(mktemp -d -t mnt.XXXXXXXXXX)
trap "[[ -z "$MNT" ]] || rm -rf $MNT ||:" 0 1 2 3 15
if [[ -f foreman.tar.xz ]] && [[ ! -f foreman.img ]]; then
echo "Creating \"foreman\" home image ..."
qemu-img create -f raw -o size=${FOREMAN_SIZE}G foreman.img
lo=$(sudo losetup --show -f foreman.img)
echo -e "n\np\n\n\n\nw" | sudo fdisk $lo ||:
sudo kpartx -asv $lo
sudo mkfs.ext4 /dev/mapper/${lo##*/}p1
sudo mount /dev/mapper/${lo##*/}p1 $MNT
sudo tar -C $MNT -Jxvf foreman.tar.xz
sudo umount $MNT
sudo tune2fs /dev/mapper/${lo##*/}p1 -U $UUID
sudo kpartx -d $lo
sudo losetup -d $lo
fi
