Description fulalas123 2023-11-15 12:10:18 UTC 
Issue: 'cp -rf' doesn't keep destination permissions.

How to replicate:
	1- have a 644 permission test.txt file in /etc/xdg/autostart
	2- have a 755 permission test.txt file in /tmp
	3- call busybox using: busybox cp -rf /tmp /etc/xdg/autostart/test.txt

Expected behavior: the new file copied should replace the original one and keep the original file permissions.

Current behavior: the new file copied replaces the original one but it also replaces its permission, and that's not the behavior of cp from coreutils (https://www.gnu.org/software/coreutils/).

I'm using busybox 1.36.1

I tried but failed to edit the issue because there's a tiny error in the steps to replicate. Here it goes:

1- have a 644 permission test.txt file in /etc/xdg/autostart
2- have a 755 permission test.txt file in /tmp
3- call busybox using: busybox cp /tmp/test.txt /etc/xdg/autostart
