I wonder if I can write a groovysh script (which uses groovy) to execute the
build system from various VMs and such.

## 14:48

Seems it can be done, I just have to make sure I avoid some newer features in
case an older groovy is used for example.

## 14:50

I could potentially for the command line write a copy of Groovy and have that
act as the primary interpreter shell for stuff such as file handling. Depends
on how shell friendly the language is with simple loops. It would be more
fitting with Java and would also be more powerful than say shell scripts. Could
also be merged into the kernel so that there is a pre-existing interface that
could be used in rescue mode for example. Groovy is Java code so it lacks
stuff such as "ls".

Actually I can have a POSIX compatible system and still have my multiple
root planned structure. POSIX has `//` as a root component which is system
specific. This means I can fill `/` with the minimum of

 * `/dev/console`
 * `/dev/tty`
 * `/dev/null`
 * `/tmp/`

Everything else including system configurations and such will basically be
based in `//@system/`. All of the volumes which are available would then be
under `//`.

The problem with Groovy is figuring out the path of the script I just executed.

## 16:15

It may be possible to do this by looking at the classpath potentially. However
this gives `/usr/share/groovy/lib/groovy-1.8.6.jar` which is not useful at all.
Looking online it may be possible that
`getClass().protectionDomain.codeSource.location.path` does this. That does
work as it gives `/home/steven/k8/hairball.gsh`. For safety I should probably
verify it and then request a system property for example.

## 18:56

I have a bit of a headache this day.

## 23:34

For some reason I cannot execute the first stage. The exit value is just
`First stage exited with status 1.`.

## 23:51

Forgot about the Process I/O streams, I have a dumper for that now. And the
result is the lack of the exedir.
