My notes for running Linux on slow/small/old systems

initramfs

You cannot really use LZ4 compression for your initramfs as the block size for LZ4 compressed initramfs is 8MB (https://elixir.bootlin.com/linux/v6.10.8/source/lib/decompress_unlz4.c#L28) and the kernel will want to allocate an 8MB buffer to work in. LZO has a block size of 256KB (https://elixir.bootlin.com/linux/v6.10.8/source/lib/decompress_unlzo.c#L36) which you might have more luck with.

Misc kernel config options

CONFIG_CRYPTO_JITTERENTROPY is very slow on 68030.
