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
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.
