# Installs the wrapper at /sbin/sysv-wrapper and symlinks the legacy
# tool names to it. /sbin/init is NOT symlinked here — that path is
# the zyginit daemon binary. If you want sysv-wrapper to handle
# `init <N>` too, move zyginit aside (e.g. to /sbin/zyginit) and
# symlink /sbin/init -> sysv-wrapper instead.
