// This file provides the loadSystemRoots func when the
// "x509omitbundledroots" build tag has disabled bundling a copy,
// which currently on happens on darwin/arm64 (root_darwin_arm64.go).
// This then saves 256 KiB of binary size and another 560 KiB of
// runtime memory size retaining the parsed roots forever. Constrained
// environments can construct minimal x509 root CertPools on the fly
// in the crypto/tls.Config.VerifyPeerCertificate hook.
