I think shutdown receives a HUP signal when the connection is terminated,
because it still has the ssh tty as its controlling terminal.
I've just done some experimenting using sleep instead of shutdown, and
found this:
- you need to omit the -t
- you need to redirect stdin/stdout/stderr
So try:
ssh host.domain.tld 'shutdown -r +90 </dev/null >/dev/null 2>&1 &'
