# FS QA Test No. 199
|
|
#
|
|
# Check that the features2 location fixups work correctly. We check both
|
|
# a regular read-write mount of a filesystem and the case where the
|
|
# filesystem is first mounted read-only and then later remounted read-write,
|
|
# which is the usual case for the root filesystem.
