- GNU coreutils does not do that - this `chown` call does not work when running with `pseudo` - this behavior was added in uutils#5735 to make the test `install-C-root.sh` pass Fixes uutils#9116 Signed-off-by: Etienne Cordonnier <[email protected]>

- `pseudo` is a tool which simulates being root by intercepting calls to e.g. `geteuid` and `chown` (by using the `LD_PRELOAD` mechanism). This is used e.g. to build filesystems for embedded devices without running as root on the build machine. - the `chown` call getting removed in this commit does not work when running with `pseudo` and using `PSEUDO_IGNORE_PATHS`: in this case, the call to `geteuid()` gets intercepted by `libpseudo.so` and returns 0, however the call to `chown()` isn't intercepted by `libpseudo.so` in case it is in a path from `PSEUDO_IGNORE_PATHS`, and will thus fail since the process is not really root - the call to `chown()` was added in uutils#5735 with the intent of making the test `install-C-root.sh` pass, however it isn't required (GNU coreutils also does not call `chown` just because `install` was called as root) Fixes uutils#9116 Signed-off-by: Etienne Cordonnier <[email protected]>
