When there's only one version of a module, allow to omit the module version.

[khfeng]

As someone who regularly remove/install dkms, I found specifying the module version is redundant in most cases.

I'd like to use dkms install <module> instead of dkms install <module>/<version>, if there's only one version of the module.

If this new behavior is acceptable and does not break scripts that already depend on DKMS, I can make a patch for this.

For someone want to use dkms install frequently ,I suggest you write your own script to do this . debug script is more helpful than change original dkms install command .

[khfeng]

I need this because I modify module source directly in /usr/src for debugging, so recompile modules is necessary in my case. I don't see debug script is helpful in this case.

In most situation ,Linux user have some dkms modules installed ,I do not think that we need to change function codes for this debuging or convenience purpose . @jared-dominguez What is your opinion on this request ?

[khfeng]

I don't think I fully understand what your concern is, but at least this kind of change won't break existing functionality.

The old behaviour (version explicitly specified) will keep working.

@khfeng Hi Kai heng. Normally, we can choose the module with quick TAB key. Then if you do not have any questions. I will close the issue after one week.

[khfeng]

I don't think you really understand what I am asking for.

To simply put: why do we need to specify version number, when there's only one version available?

[jared-dominguez]

@khfeng,

If I'm understanding right, this is entirely different from, say, https://github.com/dell/dkms/pull/5. I think the following should be acceptable:

1. User types 'dkms install [/]'
2. dkms checks /usr/src for instances 3a. If is specified on command line, note that version and continue to step 4. If no version is specified and a one version flag is specified, continue to step 3b. 3b. If only one version is in /usr/src and a module of the same name is not already installed, assume version is same as found in /usr/src and note that version number.
3. Use the version number as noted.

Because this is a behavioral change, I think we should only enable this with a flag ("-1" perhaps?). That is, I think it's okay to do this as an optional change. I don't want this to devolve into a semantic change in existing functionality like https://github.com/dell/dkms/pull/5 would be, as a semantic change could result in unintended consequences for distributions depending on DKMS.

@khfeng Hi Feng. Could you help to make the patch for this improvement?
