When launching a custom msys2 environment, and it does "first-run" operations, it complains that: "cannot change permissions of '/dev/shm': Permission denied". This is related to the previous work in this area that happened in #2337: Since "/" is mounted with noacl and chmod() is a no-op, this error is cosmetic and can be removed. However, in #2337, the access modifying behaviour was not removed from the "mkdir" branch, which this patch aims to address.
