And as said in that bug report as well, libz and numerous other
compression libraries are already added with a default initramfs-tools.

$ lsinitramfs /boot/initrd.img-5.6.0-2-arm64 | grep -E 'libz|liblz'
usr/lib/aarch64-linux-gnu/liblz4.so.1
usr/lib/aarch64-linux-gnu/liblz4.so.1.8.3
usr/lib/aarch64-linux-gnu/liblzma.so.5
usr/lib/aarch64-linux-gnu/liblzma.so.5.2.4
usr/lib/aarch64-linux-gnu/liblzo2.so.2
usr/lib/aarch64-linux-gnu/liblzo2.so.2.0.0
usr/lib/aarch64-linux-gnu/libz.so.1
usr/lib/aarch64-linux-gnu/libz.so.1.2.11
usr/lib/aarch64-linux-gnu/libzstd.so.1
usr/lib/aarch64-linux-gnu/libzstd.so.1.3.8

Your argument that only if it uses plymouth doesn't appear to be
correct:

$ dpkg -l '*plymouth*'
dpkg-query: no packages found matching *plymouth*


Given that this issue keeps coming up, I'm reopening and marking it as
"wontfix", and marking which bugs it blocks moving forward.


live well,
