# https://github.com/docker/cli/issues/4807
# As of 02/01/2024 a change in the "/etc/init.d/docker" script shipped with docker v25
# is preventing the cpi image to work.
# when start-bosh runs `service docker start` it errors with:
# "/etc/init.d/docker: 62: ulimit: error setting limit (Invalid argument)"
# disable resetting ulimit. Pre v25 the script contained `ulimit -n 1048576`
# the default in our base image is:
# ulimit | grep file
# `open files (-n) 1048576`
# so it was a noOp..
# running `ulimit -Hn 1048576` will succeed.. The issue happens when we want to raise the ulimit.
