Hi All, The master branch on the unionmount-testsuite tree [1] has been updated. Changes in this update: - Support for user configurable mount option - Prepare to run tests with "userxattr" mount option The previous update brought the ability for users to configure custom paths with a custom filesystem for the underlying layers. That ability was used to add xfstests wrappers for unionmount-testsuite. This update brings the ability for users to configure custom overlay mount options. This feature is also intended to be used by xfstests [2]. I used this ability to run tests with the new "userxattr" and "uuid=off" mount option: $ export UNIONMOUNT_MNTOPTIONS=userxattr $ ./run --ov --verify TEST rmdir.py:64: Remove populated directory - rmtree /mnt/a/dir106 OSError: [Errno 5] Input/output error: '/mnt/a/dir106/pop' $ export UNIONMOUNT_BASEDIR=/vdf # (xfs filesystem) $ ./run --ov --verify TEST hard-link-sym.py:10: Hard link symlink ./run --link /vdf/m/a/direct_sym100 /vdf/m/a/no_foo100 /vdf/m/a/no_foo100: inode number/layer changed on copy up... $ export UNIONMOUNT_MNTOPTIONS="uuid=off" $ ./run --ov --verify and came to the following observations: 1) rmdir test as well as other tests involving opaque dir are failing on tmpfs, because tmpfs does not support user.* xattrs 2) hard-link-sym test fails consistent inode number verification also on xfs, because symlink does not support user.* xattrs 3) All the other tests pass on xfs with the userxattr mount option 4) No failures observed with uuid=off I did not try to run tests inside non init userns. This practice is left to the reader. Thanks, Amir.
