From 5c726bd40a4a745e115a22e336131be8f6666b55 Mon Sep 17 00:00:00 2001 From: Samuel Mendoza-Jonas Date: Mon, 25 Feb 2019 13:47:03 +1100 Subject: utils/pb-console: Trap SIGTERM on boot On kexec all processes will be sent a SIGTERM and SIGKILL. By default there are messages on the console alerting the user to this, however in some implementations these messages are disabled. This can have the effect of the UI seemingly exiting to the shell on boot and hanging for a short while before the kexec actually jumps into the next kernel. Trap the SIGTERM sent to the pb-console parent process and print a short message to the screen instead of momentarily dropping to the shell and printing the usual help messages. While here also cleanup the shell help messages below which are now handled in the shell's .shrc file.
