[AustinAbro321]

Environment

App version: v0.47.0-v0.48.1

Steps to reproduce

1. a zarf.yaml with a component with an absolute path

components:
  - name: baseline
    files:
      - source: /home/austin/code/zarf/cosign.pub
        target: here.pub

2. build package with zarf package create

Expected result

The package builds successfully

Actual Result

2025-02-06 14:22:07 ERR failed to create package: unable to copy file /home/austin/code/secondZarf/cosign.pub: lstat home/austin/code/secondZarf/cosign.pub: no such file or directory

Severity/Priority

Medium, it seems this was already broken with imports, but allowed in the base package. It's simple enough to fix
