That surprises me. I thought the interface to the kernel would be
something a little more... orthogonal. For example...
$ grep magic /proc/sys/fs/binfmt_misc/arm-elf
magic 7f454c4601010161
The preceding would be a sensible format for the kernel interface to
me. the binfmt_misc/register interface being what it is though, I'd
agree that teaching the kernel to understand octal escape sequences
makes sense.
Cheers,
