--use-copy-link breaks GIT CLONE

[alexcb]

VERSION --use-copy-link 0.6

FROM alpine/git:1.0.7
test:
    WORKDIR /test
    GIT CLONE https://github.com/moby/buildkit.git buildkit
    WORKDIR /test/buildkit
    RUN pwd
    RUN ls -la
    RUN ls -la .git # this fails
    RUN git status
    RUN git branch
    RUN test -f README.md

However if you remove the --use-copy-link feature flag (i.e. only use VERSION 0.6), it works.

Strange... A simple solution might be to disable the copy link flag in the git clone. I think this call is the only thing used: https://github.com/earthly/earthly/blob/main/earthfile2llb/converter.go#L1280.

Though I'm not sure what the real cause of this is and whether it might impact other COPYs in subtle ways.

it looks like it's being cloned to /buildkit and is ignoring the WORKDIR.

fixed with #2273
