I've debugged it further. the issue is that apparently kiwi does some kpartx -a magic, and then later reads through /dev/mapper/* to find out about the mappings (that it just created itself). For reasons that I don't understand, the /dev inside the build chroot does not get any files inside /dev/mapper/*.
With the help from Alex we potentially found a fix: it seems the default of kpartx for "sync mode" changed between 12.2 and 12.3. changing the kpartx -a/-d calls to -sa/-sd (for enabling sync mode) might fix the issue (not fully tested yet, but a quick try looked promising). Marcus, any opinion about this patch? Thanks, Dirk
