If you are using I/O logging sudo will allocate its own pty which
the command will run in.  When sudo finishes, the command would
receive SIGHUP since the command itself is not being run under
nohup.

I would expect this to work OK if you did:

ssh -t -t user at host "sudo nohup /etc/init.d/somescript.sh"
