# We create the top-level lib symlink on merged-usr systems, so that we can
# cover cases where for example libc-i386 on amd64 is installed and then removed
# (which deletes the symlink too). Note that we only suppor the simplest case,
# no conversion (moving files) is done here, as that's the job of the usrmerge
# package. See: https://bugs.debian.org/926699
# Once all packages install only under /usr, this can be removed, as removing
# this package will no longer result in the symlink being deleted.
