Note this runs inside unshare so we can mount things.

Prepare the directories, files and mounts.

  $ mkdir -p root/mnt root/dir
  $ echo aaa > root/file1
  $ echo bbb > root/dir/file2
  $ mount -t tmpfs none root/mnt
  $ echo ccc > root/mnt/file3
  $ mkdir root/mnt/subdir
  $ echo ddd > root/mnt/subdir/file4

Generate with -x: only root device files should get checksums.

  $ alias summer="$TESTDIR/../summer"
  $ summer -v --parallel=1 -x generate root
  "root/dir/file2": writing checksum \(checksum:\w+, mtime:\d+\) (re)
  "root/file1": writing checksum \(checksum:\w+, mtime:\d+\) (re)
  0s: 0 matched, 0 modified, 2 new, 0 corrupted

Verify with -x: should see only root device files.

  $ summer -v --parallel=1 -x verify root
  "root/dir/file2": match \(checksum:\w+, mtime:\d+\) (re)
  "root/file1": match \(checksum:\w+, mtime:\d+\) (re)
  0s: 2 matched, 0 modified, 0 new, 0 corrupted

Verify without -x: root device files match, mount files are missing.

  $ summer -v --parallel=1 verify root
  "root/dir/file2": match \(checksum:\w+, mtime:\d+\) (re)
  "root/file1": match \(checksum:\w+, mtime:\d+\) (re)
  "root/mnt/file3": missing checksum attribute
  "root/mnt/subdir/file4": missing checksum attribute
  0s: 2 matched, 0 modified, 2 new, 0 corrupted

Unmount so the test directory can be gracefully cleaned up.

  $ umount root/mnt
