I would replace the ";" with "&&", since it makes no sense to continue
with the dist-upgrade, if the update should fail.
I strongly recommend not to use the "-y" option. A user always should
care about the packages that should be upgraded and then manually
confirm to continue.

That's bad, there are a few exceptions when restarting or at least
logging out and in is required, there are ways even to switch the kernel
without a restart. However, to use a new kernel it IMO is better to
restart.

It's hard to recommend how inexperienced users should handle this.
Perhaps it doesn't matter.

I recommend to run it after each remove, purge and upgrade, to keep the
list of packages overseeable.

Simply purge the package update-manager ;).
If I would install it on my Wily install, it would also install tons of
other unneeded packages.
[root at moonstudio ~]# dpkg -l update-manager|tail -n1
un update-manager <none> <none> (no description available)
[root at moonstudio ~]# apt-get install update-manager
[snip]
38 newly installed, 0 to remove and 0 not upgraded.
Need to get 9073 kB of archives.
After this operation, 41.9 MB of additional disk space will be used.
Do you want to continue? [Y/n] n
Abort.
Warning! There are different kind of computer users. All my Linux, also
my Ubuntu install are tailor-made to fit to my needs.
Inexperienced users should be aware that security upgrades are very
important and it might be better to stay with update-manager.
Assumed RAM and CPU resources or battery power are important and/or
there should be the need to avoid interrupts, e.g. to improve real-time
capability, then it might be a good idea to purge update-manager, but
first consider to disable all unneeded services. By default Ubuntu
auto-starts everything provided by a package that could be
auto-started, for sure update-manager isn't the biggest evil, if there
are reasons to care about each interrupt, each percent CPU and RAM
usage.
