name: stage2-reset-specs
kind: chunk

# Nasty hack to get around being unable to reliably add configuration to gcc,
# hence the gcc specs are modified, combined with Baserock's rootfs protection
# preventing specs being modified before builds.
# The limitation is overcome by installing files as part of a chunk, which
# overwrites previous files.
# New specs were added for the bootstrap builds, but after stage2 we start
# having chrooted builds, so the old specs need to be replaced.
# Unfortunately we can't just replace the specs with the ones gcc produces,
# since gcc behaves differently without specs to with specs it produces!
# So we use a **NASTY HACK** to replace the specs symlink with one that
# points to a file that doesn't exist.
