Subject: [PATCH] admin: Ensure correct ownership when moving to file:// uri
|
|
|
f07a28 |
|
|
|
f07a28 |
User and group is not restored properly when moving (or copying with
|
|
|
f07a28 |
G_FILE_COPY_ALL_METADATA) from admin:// to file://, because it is handled
|
|
|
f07a28 |
by GIO fallback code, which doesn't run with root permissions. Let's
|
|
|
f07a28 |
handle this case with pull method to ensure correct ownership.
