• It allows you to use relative path (relative to the yaml's location) when speficying bind sources.
• When the euid is not 0, it will ask you whether you want to use sudo.

Requirements

• python3
• pyyaml
• fchroot
• sudo (optional)

How to use

fchroot-compose <yaml file>

YAML format

funtoo-stage3.yaml is a example.

newroot: /home/marvin/stage3-latest
bind:
  - src: /home/marvin/fchroot-bind/fun-overlay
    dst: /fun-overlay
  - src: ../../fchroot-bind/pkg
    dst: /var/cache/portage/packages
  - src: ~/fchroot-bind/portage
    dst: /etc/portage

It is allowed to have multiple src/dst pairs. Relative path, and the tilde shortcut is also allowed in source paths. Dst is the chrooted path of the destination.
