Fix your initscripts?

I still boot it, once in a while.
OK; you take the cake. That ramdisk came to mind when I thought about
where I'd last seen bdflush, but I've not used it in ages (not sure 14
MB are enough for that).
Of course it will work on your 14 MiB machine! It fits on a floppy, _after_
decompression. It was used by people to install Linux on the hard disks
of their beefy m68k machines, after they had set up the family Christmas
tree, in December 1996.
Been there, done that. Wrote the HOWTO for ext2 filesystem byte-swapping.
I also have a slightly larger one, built from OpenWRT when I did my first
experiments on that. Unlike filesys-ELF-2.0.x-1400K-2.gz, it does open
a shell on the serial console, so it is more useful to me.

The question then is - will bdflush fail gracefully, or spin retrying
the syscall?
Will add to my todo list...
BTW, you can boot this ramdisk on ARAnyM, too.

True. I can't find that ramdisk image anywhere - if you can point me to some archive, I'll give that a try.

Cheers,
