That sounds like the right way to go, though you don't need to use sudo.
The calling sequence goes:
/init->/etc/inittab->/etc/rcS->/etc/init.d/tc-config->/opt/bootsync.sh->/opt/bootlocal.shIf the sequence fails before reaching bootsync.sh or bootlocal.sh you won't have network support.
Without the network, monit can not send an email, so placing it in inittab won't really buy you anything.
Even if you wanted to modify inittab and add it to your backup, I don't know if the restore function
occurs early enough in the boot process for that to work.
