Build custom packages with cuirass.

Hi,

I'm trying to use cuirass to build all the packages of my current
manifest on top of guix master periodically.

Some of my packages are custom, so I need cuirass to be aware of
GUIX_PACKAGE_PATH env variable.

The only way I found is to patch cuirass service (cf. following patch).
Is this a good idea ? Is someone doing this kind of stuff here ?

Thank you,

Mathieu
