The package ncc_reset can be used to reset ncc credentials and cache.

When calling ncc_reset the current ncc credentials and cache are
removed. Also the nu_novell_com update service will be removed.

You need to run YaST and configure online update or to run the
comamnd line tool suse_resgister to get a new update channel
afterwards.

The tool ssh_reset deletes already created ssh host keys, so each
copy of the image can create its oen ssh host keys when started the
first time.

You need to call ncc_reset and ssh_reset manually after the package install:

ssh_reset --ssh_reset
ncc_reset --ncc_reset
