i added some days ago, a search domain to my resolv.conf.
Due to a reboot (kernel 18.104.22.168
) i experienced that a lookup using that searchdomain does not work anymore. The problem was the line "search ..." that i added to the resolv.conf disappeared. But i did not change anything, i mean the kernelinstall normally does not affect the resolv.conf (or does it nowerdays?) so only the (re)start of services could be the problem.
So the question is, does ISPConfig write to the resolv.conf and if yes, where can I change the template / or which script is responsible for that?
