It won't remember anything across reboots, so you need to create a file to store the state in.

Code:
#!/bin/bash

[ -f /path/to/state ] && STATE=$(cat /path/to/state)

case "$INSTALLSTATE" in
INSTALL)
        # continue install stuff
        ;;
*)     if apt-get update 
        then
                echo "INSTALL" > /path/to/state
                /sbin/reboot
        else
                echo "update failed" >&2
                exit 1
        fi
        ;;
esac

As for how to start it on reboot, you'll need to put it in your distro's equivalent of /etc/local.start . Making a full-fledged service for it would probably be overkill. Or if you want it to start on login, perhaps the users' .profile or .bashrc

Unless you're updating the kernel, why's a reboot needed?

reboot(3C)																reboot(3C)

NAME
reboot - reboot system or halt processor SYNOPSIS
#include <sys/reboot.h> int reboot(int howto, char *bootargs); The reboot() function reboots the system. The howto argument specifies the behavior of the system while rebooting and is a mask con- structed by a bitwise-inclusive-OR of flags from the following list: RB_AUTOBOOT The machine is rebooted from the root filesystem on the default boot device. This is the default behavior. See boot(1M) and kernel(1M). RB_HALT The processor is simply halted; no reboot takes place. This option should be used with caution. RB_ASKNAME Interpreted by the bootstrap program and kernel, causing the user to be asked for pathnames during the bootstrap. RB_DUMP The system is forced to panic immediately without any further processing and a crash dump is written to the dump device (see dumpadm(1M)) before rebooting. Any other howto argument causes the kernel file to boot. The interpretation of the bootargs argument is platform-dependent. Upon successful completion, reboot() never returns. Otherwise, -1 is returned and errno is set to indicate the error. The reboot() function will fail if: EPERM The {PRIV_SYS_CONFIG} privilege is not asserted in the effective set of the calling process. intro(1M), boot(1M), dumpadm(1M), halt(1M), init(1M), kernel(1M), reboot(1M), uadmin(2) 22 Mar 2004 reboot(3C)
