   4 Subject: [PATCH 1/7] Prevent manual builds in the DKMS source.
   5
   6 Print an instructive error messsage and exit if the `dkms.conf` file
   7 exists when the userland is configured. (ie: `--with-config=user`)
   8
   9 A non-trivial number of people try to rebuild ZoL from the
  10 `/usr/src/zfs` tree, which is modified to better satisfy Debian
  11 packaging policy and contains only the module sources for DKMS.
  12
  13 Regardless, local installations usually break managed installations,
  14 so this autotools test could be further enhanced to check whether
  15 ZFS has a DKMS registration.
