Comment 4 for bug 1868129

FTR, on Archlinux this option is also not used, however the `--type writecache` works fine. So either something changed in later versions, or it might be that some other `configure` option is needed. The Archlinux `lvm version` output is:

     λ lvm version
      LVM version: 2.03.12(2) (2021-05-07)
      Library version: 1.02.177 (2021-05-07)
    /dev/mapper: mkdir failed: Permission denied
    Failure to communicate with kernel device-mapper driver.
    Incompatible libdevmapper 1.02.177 (2021-05-07) and kernel driver (unknown version).
