Not working with WSL about pakkero

[89luca89]

Seems to be for starters an incompatible flag between base64 from BSD coreutils and GNU Coreutils,
try installing base64 from GNU coreutils using this project:

https://github.com/fabiomaia/linuxify

EDIT: Obviously any PR is welcome :)

EDIT2: the -w flag is the culprit, it's needed to have a one-line base64 string, but it's exclusive to the GNU Version of base64
EDIT3: And the strip flags also, needs the GNU/Linux version for those flags

Hi @aidenesco , I did not test on WSL, will test and try to see if I can reproduce the issue

Is it WSL1 or WSL2?

@89luca89 Where did you test this on? maybe would be nice to have a Dockerfile to avoid this type of issues. I can't get it to work on MacOS. Thanks a lot for this awesome project BTW.

EDIT: Nevermind, just saw that you did a release for Linux AMD64.

Reopening the issue, the idea of a Docker image for the packer part is appealing

@alfonmga you were referring to the packer part or to the launcher part?

[89luca89]

Expanding on this, the packer part should work fine in a docker image (and could work in any unix I think, but have not tested)

The launcher part is highly tied to Linux as it runs on specific raw syscalls

The launcher part. It fails when I run make on $GOPATH/src/github.com/89luca89/pakkero to build:

I'm going to try to use Docker to fix this, if my Dockerfile looks good enough I'll create a PR so you can add it to the repo.
