Description Erik Damrose univentionstaff 2013-04-09 13:06:06 CEST 
+++ This bug was initially created as a clone of Bug #30441 +++

Setup:

UCS Master and UCS Slave, DHCP DNS Policy with both hosts as nameservers and a
UCC Client with ldap/server/addition set to the slave.


Booting the client if the master is down takes about 5 minutes. 

---
The initial bug has been partly fixed by starting the loopback interface in the initramfs script ucc. Remaining big delays are the result of 3 scripts that each create a ldap connection and have to wait for a timeout when the ldap master is not available and when the first dns server (the master) is unreachable. Each script runs for about 20 seconds contrary to a 3 second runtime when the client is booted (due to DNS being handled by dnsmasq).

generate_upgrade_script
univention-ucc-boot-option
get_boot_mount_option.sh

The 3 scripts should be merged into one script that is called in the initrd to greatly reduce boot time.
