Issue or Feature Request:
Spotted this in bottlerocket-os/bottlerocket#1799 (comment) - the SDK has some directories owned by builder that should be owned by root.

[builder@b9e9b9e0f2db /]$ ls -latr / | grep builder
drwxr-xr-x.   3 builder builder 4096 Nov 16 22:58 x86_64-bottlerocket-linux-musl
drwxr-xr-x.  14 builder builder 4096 Nov 16 22:58 usr
drwxr-xr-x.   3 builder builder 4096 Nov 16 23:01 x86_64-bottlerocket-linux-gnu
