commit ae992e68d3ed7a177adea8b9afa4ec88c27254f0 Author: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> AuthorDate: Tue Sep 9 18:06:37 2025 +0100 Commit: Andrew Cooper <andrew.cooper3@xxxxxxxxxx> CommitDate: Wed Sep 10 17:19:50 2025 +0100 CI: Create initrd fragments explicitly as root We have a mix of root and non-root containers, and are trying to become rootless. This can cause the local CPIO fragements to end up being user:user in the test environment. Nothing seems to go wrong so far, but it's a trap waiting to happen. Make everything consistently root for the initrds, irrespective of the rootness of the container the test is running in. No practical change.
