Running tini with subreaper on aws lambda

[yaron12n]

I'm trying to use tini -s on my aws lambda. Getting this error Failed to register as child subreaper: Operation not permitted Probably beachuse prctl(PR_SET_CHILD_SUBREAPER) is not allowed on lambda.

Is there any workaround I can do to make this work? PID 1 is not possible because the lambda has it's own And prctl isn't allowed for the lambda.

Based on your description of the problem, I don't see how tini can operate within those limitations. I see a few alternative options:

1. make your process reap its own children (i.e., don't make zombies by handling SIGCHLD)
2. don't run long enough for zombies to matter
3. hope that lambda's PID 1 reaps zombies
