/sysroot/etc/inittab: Not such file or directory after upgrading to v3.17

Making a customized ISO no longer works: everything worked perfectly with version 3.16, but after upgrading to version 3.17 there are some errors.

I get the following error on boot:

... and when building with mkimage (ERROR: ...):
