What's the > contents of the upper and lower filesystems? in the sed case, the file exists in the lower filesystem and is copied to tmpfs, removed and moved from tmpfs to the original file; several times the same operations are done. in the package upgrade, the file does not exists, it is created on tmpfs and moved to the final overlayfs directory; after we can check that it does not exist there. As I thinked previously, the common operation that appears in both processes and maybe the cause of the problem is move from another filesystem to overlayfs.
