Subject: [PATCH] Remove capabilities instead of setting empty caps via.
|
|
|
83a7c7 |
--setcaps
|
|
|
83a7c7 |
|
|
|
83a7c7 |
If a file in a package does not have any capabilities rpm --setcaps should
|
|
|
83a7c7 |
remove capabilities of the file. Prior to this patch capabilities of the file
|
|
|
83a7c7 |
were set as empty.
|
|
|
83a7c7 |
|
|
|
83a7c7 |
Empty capabilities mean more than no capabilities. A file with no capabilities
|
|
|
83a7c7 |
can inherit capabilities, but file with empty capabilities can not.
|
|
|
83a7c7 |
|
|
|
83a7c7 |
When ever package does not have any capabilities set %|FILECAPS? is false.
|
|
|
83a7c7 |
If some files have capabilities, %|FILECAPS? is true but %{FILECAPS} is ''
|
|
|
83a7c7 |
when the file does not have capabilities and '= <capstring>' when there is some.
