 ## Modules ##
  - The *users* module no longer wrote `/etc/hostname` at all.
  - The *users* module erroneously shows the root password input fields.
+ - The *initramfs* module sets a resume-hook even when there is no swap.
+ - The partitioning service expects *udevadm* in `/sbin`, but some
+   distro's place it elsewhere.
+ - The mount service didn't unmount directories properly, leading to
+   blocked installations.
