- // For example, if someDir=/mnt/vol1/gitea-home/data, if the mount point /mnt/vol1 is not mounted when Gitea runs,
- // then gitea will make new empty directories in /mnt/vol1, all are stored in the root filesystem.
- // The correct behavior should be: creating parent directories is end users' duty. We only create sub-directories in existing parent directories.
- // For quickstart, the parent directories should be created automatically for first startup (eg: a flag or a check of INSTALL_LOCK).
- // Now we can take the first step to do correctly (using Mkdir) in other packages, and prepare the AppDataPath here, then make a refactor in future.
