7.5.3 Distributing Images to Point of Service
Terminals
New or updated images are distributed to Point of Service terminals at boot time. For
information on this process, see Section 7.8, “Booting the Point of Service Terminal”
(page 102).
7.5.4 Image Install Notification
When the Branch Server distributes a new image to a Point of Service terminal, the
system provides notification that the image was successfully installed on the Point of
Service terminal. The notification is stored in the
scWorkstation
object in the
LDAP directory on the Administration Server.
When the image is successfully installed on the Point of Service terminal, the
linuxrc
script running on the Point of Service terminal creates the
bootversion
.
MAC
file
in the
/srv/tftpboot/upload
directory on the Branch Server. The posleases2ldap
process then transfers the information to the
scNotifiedimage
attribute in the
scWorkstation
object in LDAP and deletes the
bootversion
.
MAC
file.
7.6 Hardware
Point of Service terminals are implemented in a variety of hardware forms. The primary
difference in Point of Service hardware is whether the terminal has an internal hard
drive or other persistent media (such as a flash drive), or whether the terminal is diskless.
A system that has a hard disk can be configured to store the image on a disk partition
instead of a RAM disk so it can boot from the hard disk if it cannot boot over the net-
work.
7.6.1 Hardware Configuration Files
Point of Service terminal hardware configuration information is either stored in LDAP
as
scConfigFileTemplate
objects, or on the Administration Server as a file and
distributed over rsync. Hardware configuration files that are distributed by the Admin-
