Installing xz and busybox together may cause conflicts for xz, xzcat,
unxz, and their lzma variants. In the default configuration, xzcat is
silently replaced with a symlink to busybox. If busybox is compiled with
CONFIG_XZ=y, its postinst fails during do_rootfs.
Using update-alternatives to xz handles these conflicts properly.
