    ACK bfe1ba2f5b36056e0c41edf8206b93d3d83098df - I agree with Carl, and am going to merge this. I'd like for Linux Guix builds to be working again, and we can rebase #18818.

** INT received while building ${1}, you may want to clean up the relevant
output, deploy, and distsrc-* directories before rebuilding
Hint: To blow everything away, you may want to use:
$ git clean -xdff --exclude='/depends/SDKs/*'
Specifically, this will remove all files without an entry in the index,
excluding the SDK directory. Practically speaking, this means that all ignored
and untracked files and directories will be wiped, allowing you to start anew.

# Explanation of `guix environment` flags:
#
# --container run command within an isolated container
#
# Running in an isolated container minimizes build-time differences
# between machines and improves reproducibility
#
# --pure unset existing environment variables
#
# Same rationale as --container
#
# --no-cwd do not share current working directory with an
# isolated container
#
# When --container is specified, the default behavior is to share
# the current working directory with the isolated container at the
# same exact path (e.g. mapping '/home/satoshi/bitcoin/' to
# '/home/satoshi/bitcoin/'). This means that the $PWD inside the
# container becomes a source of irreproducibility. --no-cwd disables
# this behaviour.
#
# --share=SPEC for containers, share writable host file system
# according to SPEC
#
# --share="$PWD"=/bitcoin
#
# maps our current working directory to /bitcoin
# inside the isolated container, which we later cd
# into.
#
# While we don't want to map our current working directory to the
# same exact path (as this introduces irreproducibility), we do want
# it to be at a _fixed_ path _somewhere_ inside the isolated
# container so that we have something to build. '/bitcoin' was
# chosen arbitrarily.
#
# ${SOURCES_PATH:+--share="$SOURCES_PATH"}
#
# make the downloaded depends sources path available
# inside the isolated container
#
# The isolated container has no network access as it's in a
# different network namespace from the main machine, so we have to
# make the downloaded depends sources available to it. The sources
# should have been downloaded prior to this invocation.
