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 <[email protected]>

This reverts commit 0c19129.
Creating this PR also for discussion, as we think the current behavior is wrong and not fitting the design defined in the manpage.
Per man dkms, the
uninstallcommand should leave the uninstalled modules in the 'built' state and only removed after runningremove. After this commit it seems that dkms uninstall started to remove the modules from the built tree, making them no longer stay in the 'built' state (they're not reported as such anymore).This caused a regression in Ubuntu 19.04 where some of our other packages expected things to work as per the manpage. Quoting:
"Uninstalls an installed module/module-version combo from the kernel/arch passed in the -k option, or the current kernel if the -k option was not passed upon. After uninstall completion, the driver will be left in the built state.
To completely remove a driver, the remove action should be utilized."
Without this change reverted, this does not seem to be the case anymore. After the revert,
dkms uninstallseems to work as expected (and as it previously did). What was the rationale for the original change? What use-case was it fixing? The change description wasn't very descriptive.Thank you!
