On ARAnyM, I could boot a 4 MiB initrd (note that ARAnyM doesn't seem to
support gzipped ramdisks!), created by appending zeroes to the good old
filesys-ELF-2.0.x-1400K-2, and running resize2fs.
It even worked with a 32 MiB initrd, after increasing xx to 32768.
Haven't tried with the Amiga yet.

In personal conversations with technical people, I call myself a hacker. But
when I'm talking to journalists I just say "programmer" or something like that.
