UCS 2.4 - Univention

3.4 Installing and Renewing Licences
the necessary kernel drivers (for hard drives, Ethernet adapter, etc.) have to be declared manually in the
UCS Installer.
The boot parameter loadmodules can be used at the boot prompt for including certain kernel drivers into
the list of drivers to be loaded (e.g. for a profile-based installation). This parameter can consist of several
kernel drivers. The individual drivers are to be separated by blanks:
loadmodules="driver1,driver2,driver3"
In some cases it might be necessary to suppress the loading of certain kernel drivers. The boot parameter
excludemodules prevents the declared kernel drivers from being automatically loaded during hardware
detection. When excluding several kernel drivers, the individual drivers are to be separated by commas:
excludemodules="driver1,driver2,driver3"
Attention:
When loading kernel drivers, the kernel treats hyphens ’–’ and underlines ’_’ which might be included in
the driver names, as synonymous. This means, when using loadmodules, no difference has to be made
between usb-storage and usb_storage. excludemodules, in contrast, requires the accurate spelling in
the present use of the kernel. The relevant kernel drivers should therefore be declared in excludemodules
using both spellings (hyhpen only or underline only):
excludemodules="usb-storage,usb_storage"
3.4 Installing and Renewing Licences
The licence is installed in the Univention Directory Manager. For this purpose, the About dialogue is to be
called as the user Administrator in Univention Directory Manager. Here, the licence file can be selected
by clicking on the Search button. After confirming via the Load file button, the file is transferred to the DC
Master and installed. Then after successful installation, a renewed login at Univention Directory Manager
Manager is necessary. Then the information on the installed licence can be viewed via the About dialogue.
3.5 Subsequent Installation of Software
UCS is based on Debian which is the most frequently used Linux distribution in the professional sector.
The advantages of Debian - and thus also of UCS - include a very flexible and well thought-out package
management.
The DVD used to install UCS contains packages for the installation of the UCS base system and packages
for the different roles of a UCS computer (e.g., DC master, DC backup, DC slave, member server, managed
client). In addition, the UCS DVD also includes other packages which are not required for the operation of
UCS, but do expand UCS with practical functions.
If additional packages are to be installed on an Univention Corporate Server system, it is recommended to
browse the DVD first to see if the desired functionality can be provided by one of the available packages.
The advantage of using the programs supplied is that their compatibility with UCS has already been con-
firmed by Univention. On request, Univention can also offer further packages in many cases.
