Thanks for that, I'm still trying to digest that bite. I'm sorry for
being a bit slow on Guile.

It is for the packages which you may want to use interactivelly in
case of failure or for some extra initrd hacking you may not want/be
able to write in Guile.

Features like
- extra authentication
- full disk encryption
- root on NFS
- LVM :)
- ...

when kernel+initrd is booted from another source.

I agree that it is more for debugging and to balance my inability to
express it in Guile but it lowers the barrier a bit.

Bournish is too young to rely on it. I miss pipes, accessing files in
different directories or `ls' with wildcards. I can put in minimal
static busybox which is more than sufficient for rescue, problem
analysis or even data recovery.

I like the idea of Bournish but I'd rather have an alternative
until it is more capable.

And yes, it could be also used from Bournish in interactive session as
a command.
