I don't worry about memory usage because, according to xz's manpage,
it simply can be solved by adding 'export
XZ_DEFAULTS=--memlimit=64MiB"' (or 32MiB or even lower based on your
box's spec) to your ~/.bashrc.

1. Considering lately there's monthly (if not weekly) security update
on linux kernel, it's not so "infrequent".
2. And, it's very annoying that for one "apt upgrade", the
update-initramfs may be triggered for many times, because of upgrading
other kernel related pkg such as flash-kernel / initramfs-tools.
