+=== Repacking old software ===
+When you create RPM packages for software that you don't build from sources (like some old OS/2 programs that are only available in the binary form), you need to follow a special procedure in order to preserve the sizes and timestamps of the original files (which may be important for their identification in case if someone needs that).
+
+ 1. Add the following to the .spec file (somewhere before the %install section):
+{{{
+# disable lxlite compression
+%define __os_install_post       %{nil}
+}}}
+ 2. Use
+{{{
+cp -Rdp <src> <dst>
+}}}
+  in the %install section when you copy files from BUILD to BUILDROOT for getting packed by rpmbuild; the naked cp command will kill the original timestamp (the <dst> file will get the current time).
+
 === CONFIG.SYS changes ===
 It is sometimes necessary to modify the CONFIG.SYS file during installation, even when using RPM. One of the examples is when your package installs a device driver that needs to be loaded at boot time or when a global environment variable needs to be set. This can be done from the {{{%post}}} section using the special macro {{{%cube}}} which is based on the CUBE tool.
