Hi Liam,

rebooting after each upgrade at least makes the hard disk drives spin
down and up, in other words it causes unloading and loading the heads
and this will shorten the lifetime of hard disk drives, while rebooting
without a good reason, doesn't gain something useful. I suspect that
assumed an upgarde requires a reboot, there will be a warning a user
won't miss, assumed the user doesn't use "assume yes" options.

Not replacing the ";" with "&&" between update and dist-upgrade is ok
too, as well partial upgrades that require missing dependency upgrades
won't happen, assumed an update should fail. Anyway, it's preferable
that users get used to ensure, that all index files were re-synced. Good
habits one day might be helpful, if for what reason ever, a user
should migrate to another distro or unix-alike operating system.
Avoiding "assume yes" options is best practices what ever distro,
operating system, application is used. As a matter of principle, spending
a few seconds to read a few words, even if a users shouldn't understand
everything, doesn't harm, so users e.g. don't miss warnings. Btw. how does
"assume yes" act, if a package starts a script that requires interaction
to set up configurations? For good reasons, the Ubuntu default is _not_ to
assume yes.

To use a new kernel I prefer to reboot, anyway, there is a FLOSS method
available to switch to another kernel without rebooting.
