Then, the "anymore" part is not related with package upgrade, which
causing the menu.lst (NOT menu.1st) to be overwritten. Hence, it is
not a proper logical argument to overruled menu.lst updated.

In that case, it is quite certain that "is not connected to the
Internet anymore" is irrelevant to package/kernel upgrade, which is
done when there is internet connection.

Nope. The update is done during package upgrade. May be you come from
MS windows logical thinking i.e. certain upgrade is done during
shutdown. What I understand, in ubuntu all upgrades are done during
package upgrade, using either preinst script or postinst script in the
package (and may be other scripts as well). If you want to
troubleshoot, look at those script and not the shutdown script.
