With the procedure, all could be done automatically ;-)) No, you are wrong, the critical is not only the kernel, all running program are still in memory as well as all used libraries. Furthermore there could exist some problem with living application because they lost essential files which where not opened, this is still a somewhat critical environment which need a reboot (of course when updating only some packages this is a no do, but for upgrading from a whole distribution to another one, it is recommended to reboot even if the system is still useable). If you start new programs or still existing applications, newer applications and libraries are loaded in memory but the old are kept. > Merry Xstmas !!!
