# so far, we created desired image. Now, we make it writable by user id 1000 that is the user id which runs the notebook.
# so it is possible to install packages via fakeroot/sudo.

FROM scratch

# this is compatibility with Kaniho builder, for docker, it is enough to use: COPY --chown=1000:100 --from=base / /
COPY --chown=1000:100 --from=base  /bin /bin
COPY --chown=1000:100 --from=base  /sbin /sbin
