We want to atomically update the file to minimize the risk of an incomplete file being left behind in case of a crash, or an incomplete file being accessed while the update is still in progress. `O_TRUNC` doesn't allow that, unfortunately. While some container setups may have such permission issues, it's definitely possible to set up a container where bst inside the container runs as the same user as the owner of the .bst files. Atomic file replacement by renaming a newly created file is widely done and nothing exotic. I thus consider this an issue in the container setup and not a bug in BuildStream, so I'm closing this. If you encounter this issue by following container setup instructions in the BuildStream website, please reopen this (or open a new issue) so that we can fix the instructions. -- This is an automated message from the Apache Git Service.
