Example from README does not work

[bitfehler]

The README contains the following example:

sudo ./alpine-make-rootfs \  # (1)
    --branch v3.8 \  # (2)
    --packages 'ruby ruby-bigdecimal sqlite' \  # (3)
    --timezone 'Europe/Prague' \  # (4)
    --script-chroot \  # (5)
    example-$(date +%Y%m%d).tar.gz - <<'SHELL'  # (6)
        # Copy some file from the repository root to the rootfs.
        install -D -m 755 examples/hello_world.rb /app/hello_world.rb

        # Install some dev packages and gem mailcatcher.
        apk add --no-progress -t .make build-base ruby-dev sqlite-dev
        gem install --no-document mailcatcher

        # Clean-up dev packages.  (7)
        apk del --no-progress .make
SHELL

I cannot get something like this to work, and here is what I think is happening: when reading the script from stdin, it gets written to a temporary file and the SCRIPT variable gets set to the path of that file: https://github.com/alpinelinux/alpine-make-rootfs/blob/8516728e3d09a4ba1049340cdeaa29a4b7373ad3/alpine-make-rootfs#L335-L337 When chrooting, whatever directory the SCRIPT is in (so, in this case, the temp directory, likely /tmp) gets mounted into the chroot's /mnt: https://github.com/alpinelinux/alpine-make-rootfs/blob/8516728e3d09a4ba1049340cdeaa29a4b7373ad3/alpine-make-rootfs#L430 However, the temp directory obviously does not contain the files from the repo, so stuff like the install ... will not work.

I am not sure if I am missing something here? I was also wondering if #1 was potentially related, but it is a little... sparse on details :wink:

When using an actual file as script, everything works as expected. But of course only as long as that script is in the same directory as the files I want to copy. I suppose this is mainly a documentation issue? Also, I wanted to make sure I am not mistaken about anything. Any hints would be much appreciated, I'd even volunteer for a PR once I know the desired state of this.

:wave: just wanted to point out that this was not actually fixed with the referenced commit (thanks for merging, though :cat: )
