a dumb query? pls humor me

Hi all

Potentially a dumb query but I just don't know, and there doesn't seem 
to be any documented discussion I can read, so pls humor me on this:

after Etch has done its daily update via update mngr, is it generally 
considered a wise thing to reboot the computer to check the take or can 
one have a reasonably good degree of confidence that as far as is 
reasonable to predict, all will be well?

Thanks
