Function temporaryDirectoryForBigFiles

internal/tmpdir/tmpdir.go:25–36

TemporaryDirectoryForBigFiles returns a directory for temporary (big) files. On non Windows systems it avoids the use of os.TempDir(), because the default temporary directory usually falls under /tmp which on systemd based systems could be the unsuitable tmpfs filesystem.
