# xsysroot/refresh-sysroot.sh - (re)export the cross sysroot from the container into WSL
# ~/sysroots/arch-kde-mgl and install the toolchain file as ~/sysroots/aarch64-arch.cmake.
# Read-only on the container side (it only tars headers/libs into /root and moves the tarball out).
# Run once on a new machine, and again after the container upgrades glibc/gcc/vulkan/libdrm/gbm;
# then `bash xbuild.sh --reconfigure`.  Env: CHANNEL (default xr), WSL_DISTRO.
