I mentioned this to Perry previously, but want to mention it publicly too. That open Debian bug should be closable after this @yuzaipiaofei merges this pull request. |

Add an action "unbuild" to align with the existing "build" one. This provides for a complete symmetry - add/remove, build/unbuild and install/uninstall. Apart from the seeming cosmetic affect, this function is required when the binary kernel module(s) produced with "dkms build" must be pruned. Without this command that is not possible since using: - "dkms uninstall" will remove the symlinks/copies produced with "dkms install", while - "dkms remove" will erase all references of the dkms module. Hence "dkms status" will have no references about the module. This allows for a proper fix for dell#20 while avoiding regressions like dell#77 Signed-off-by: Emil Velikov <emil.velikov@collabora.com>
