Problem running post-install step. Installation may not complete correctly
Error running chkconfig --del alfresco : insserv: warning: script 'alfresco' missing LSB tags and overrides
insserv: warning: script 'alfresco' missing LSB tags and overrides
insserv: Default-Start undefined, assuming default start runlevel(s) for script `alfresco'
insserv: There is a loop between service RALUS and alfresco if stopped
insserv: loop involving service alfresco at depth 2
insserv: loop involving service RALUS at depth 1
insserv: Stopping alfresco depends on VRTSralus.init and therefore on system facility `$all' which can not be true!
insserv: loop involving service apache at depth 4
insserv: exiting now without changing boot order!
/sbin/insserv failed, exit code 1
I have never run into these specific issues. It looks like SLES is detecting a loop in dependencies between Alfresco and RALUS. I find that odd, since Alfresco includes its own dependencies in the installation. Perhaps it's the MySQL dependency you opted for? I don't know enough about RALUS to give any better hint.
It looks like no one else knows the answer either, given that you haven't received much response in the other places you have posted[1].
I suggest you change approaches. Your immediate problem appears to be caused by the init script. The installer has an option to not install the init script. You can then start it manually from the alfresco.sh script, which can be added to rc.local to start at boot.
