[Bug 1404302] Re: liblttng-ust0 Error opening shm /lttng-ust-wait-5
What I did for UAL is turn them on with an environment variable. That
way we can still test the production images but we don't have to get
errors with confined apps.

Title:
liblttng-ust0 Error opening shm /lttng-ust-wait-5
Status in Platform API:
New
Status in QT Ubuntu:
New
Status in ust package in Ubuntu:
Confirmed
Bug description:
Confined apps don't have access to this and continuously produce this
error message in stderr:
libust[31283/31285]: Error: Error opening shm /lttng-ust-wait-5 (in
get_wait_shm() at lttng-ust-comm.c:958)
This is printed to the application's log about once every other second and makes it hard to read the application's own debug output. For a better app developer experience this message should be silenced.
