Did you forget the attachment? Or did the mailing list strip it?

Anywhere you set with = is a 'hard' assignment which we cannot override.

Several of hobs settings are in hob-post.conf, if they have already been
hard assigned in a configuration file which is parsed earlier we cannot
override it.

If you set the IMAGE_FSTYPES with ?= setting them from the GUI should world.

Please be aware we're working to resolve such issues for hob in Yocto 1.2.
