# Package archives in the offline mirror are already zstd-compressed. Storing
# them in an outer stream saves little space but makes pacman decompress the
# outer layer while hashing and extracting every package during installation.
#
# Everything else in the live root is zstd rather than xz. Squashfs decompresses
# on the page-fault path through a single stream (CONFIG_SQUASHFS_DECOMP_SINGLE),
# where xz manages ~100MB/s against zstd's ~900MB/s, and the live root is read
# cold on every boot: kernel, plymouth, systemd, python, archinstall, gum. The
# whole ISO grows well under a percent for it, and dropping the x86 BCJ filter
# also removes one of the blockers listed in plans/aarch64-support.md.
