zypper writes logs relative to the --root directory and not in the default location about zypper HOT 4 CLOSED

No. The zypp/history belongs to the system. It is the history of package installs and removals performed by libzypp (i.e. zypper, YAST, PK, .. ) on that system. It would not make sense to store this outside the system. It's kind of similar to the rpm database, which is present even if you don't install rpm itself in the chroot.

The zypper.log file is stored as expected in the system where zypper was called, and not in the target system.

It is also intended that the file stays on the system even if libzypp itself is removed. There is no convenient way to disable this, but mabe kiwi already uses a custom zypp .conf:

Try creating a custom zypp.conf and set history.logfile=/dev/null in the [main] section.
To use the custom zypp.conf export ZYPP_CONF=<the location of the custom zypp.conf>.

@dcermak Does this work for you?
