That gives:

With zstd:
# file initrd*
initrd.img-5.10.0-7-amd64: ASCII cpio archive (SVR4 with no CRC)

# l initrd*
-rw-r--r-- 1 root root 26M May 30 06:21 initrd.img-5.10.0-7-amd64


Changing to gzip:
# update-initramfs -u
...


# file initrd*
initrd.img-5.10.0-7-amd64: ASCII cpio archive (SVR4 with no CRC)

# l initrd*
-rw-r--r-- 1 root root 33M May 31 15:54 initrd.img-5.10.0-7-amd64


Cheers,
Chris.
