Why Yast wants to install SMS when I install the DHCP service on OES2? can I at least disable it afterward?

From Yast2 : "Novell DHCP (Dynamic Host Configuration Protocol) uses eDirectory to provide configuration parameters to client computers and integrate them into a network.
The eDirectory integration lets you have centralized administration and management of DHCP servers across the enterprise and lets you set up DHCP subnet replication via Novell eDirectory.
This service selects and installs these services:
  • Novell Backup / Storage Management Services (SMS)
  • Novell eDirectory
  • Novell Linux User Management (LUM)
  • Novell Remote Manager (NRM)
