Hi Stefan,

No problem - I should have taken a closer look: 'update-ids-ruleset'
seems to be missing in the Core update for Core164, I was still using
the old version from Core163. ;-)

See:
https://git.ipfire.org/?p=ipfire-2.x.git;a=tree;f=config/rootfiles/core/164/filelists;h=c81a06294cd3527b9b68d1352d487bf1c8f95c9e;hb=refs/heads/core164
