Duplicates (aliases) will make life worse for whom? In what way? On
what evidence? The present nomenclature is idiomatic to virsh and is
a variance with how many people think of managing a host whether
virtual or not. On the other hand, one does not customarily speak of
rebooting a network or a storage array, at least not in my experience.

Then change start to boot and be done with it. But, the issue really
is what English words are commonly associated with each other in the
context we are dealing with. I submit that 'start' is not intuitively
associated with 'shutdown' by the vast majority of English speakers
and hardly associated with 'reboot' by any.
Consider the syntax of 'initctl' and 'service'. Initctl uses start,
stop and restart. Service scripts virtually without exception use
start, stop and restart, including that for libvirtd. Operators are
far more likely to be familiar with this combination of terms than any
other. Why force them to learn yet one more variant? What is the
advantage for the users?
