If I log into a host via ssh from my workstation then I can enter this:

shutdown -r +90&

and log out.  The shutdown command will continue in effect and will
activae 90 minutes later.

However, if I do this instead:

ssh -t host.domain.tld 'shutdown -r +90&'

then the shutdown command does not remain in effect.  Why is this so
and is there some way to achieve this?
