# The Void rootfs is a flat "./"-prefixed FHS archive (./bin ./etc ./usr ...), so it needs no
# --strip-components — verified against void-aarch64-ROOTFS-20250202.tar.xz. It is usr-merged
# (./bin, ./sbin, ./lib are symlinks into ./usr), which tar reproduces faithfully; peacock-init
# still finds /sbin/init because that relative symlink resolves inside the flavor root.
#
# Compression is XZ, not gzip. `tar -xpf` auto-detects it, but only if the extracting tar has xz
# support — BusyBox needs CONFIG_FEATURE_SEAMLESS_XZ (on in `make defconfig`, which is what
# peacock-ports/base/busybox builds with). The explicit fallbacks below cover a tar without it, and
# the failure message names the real cause rather than a generic "extract failed".
