When attempting to netboot subiquity on a Cavium ThunderX CRB2S, the
system always times out downloading the initrd - see below. It seems the
initrd, which is LZ4 compressed to 87M, is just too large. If I
recompress the initrd using lzma - shrinking it to 44M, I am able to
boot it. While that successfully works around the issue, I wouldn't
expect the average user to know to do it.

                         GNU GRUB  version 2.04
