Public bug reported: Currently, an easyprof-generated profile will list the reads with `rk` and the writes as `rwk`. With recent Qt, this breaks because newer Qt versions use hard-linking of temporary files to perform atomic writes. Also, `rk` doesn't allow mmap()'ing shared library for execution.
We at UBports are carrying a patch in Ubuntu Touch which changes the read rules to `mrk` and write rules to `mrwkl`, and are upstreaming this patch at [1]. When the MR is merged, I would like this patch to be included in Ubuntu 24.04, so that Ubuntu Touch doesn't have to package AppArmor separately from Ubuntu. If we agree that we want this patch, I can provide an MR on Salsa.
