# xdeploy.sh - install the WSL cross-built libMobileGL.so + mobilegl_gbm.so into the container, exactly
# like anland's anland-build-client.sh: copy to a NEW inode and rename into place (overwriting a mapped
# .so in place crashes every running client, KWin included), refresh the libEGL/libGL aliases, the
# glvnd GLX vendor link, the EGL vendor JSON (system-wide 10_mobilegl.json + the /opt copy), the client
# config /etc/mobilegl/client.conf and the GLX/GBM selection drop-ins.  Does not restart anything: already-running clients
# keep the old inode; restart the client (or the session) to pick up the new library.
# Env: MGL_XBUILD_DIR (WSL build dir), CHANNEL (ct.sh channel, default xd), WSL_DISTRO.
