[opensuse-factory] wicked: is there an equivalent to ifup/ifdown's POST_UP_SCRIPT/PRE_DOWN_SCRIPT?

Hi there, I'm currently using Factory version 20141011. The wicked network service is creating some headache for me. I used to use the PRE_DOWN_SCRIPT and POST_UP_SCRIPT variables in ifcfg-<dev>, but it appears that they are no longer supported by wicked. FWIW, my scripts added some virtual IP aliases depending on if the machine was booted in "server" or in "client" mode. Is there any equivalent available? TIA, cheers. l8er manfred
