Fine tuning of usm for newcomers: your suggestions

[Bogomips]

As it stands at the moment USM is configured with MODULES=false in /etc/usm/usm.conf. As a result if a package has no dependencies there is no option to produce a module within USM's epilog. However with MODULES=true one gets a whole load of dependencies made into modules, upon choosing download into a subfolder.

Code: Select all

root@porteus:/home/guest# grep MOD /etc/usm/usm.conf

This is a waste of time if one just requires the packages, which is much more likely than wishing to have each of dependency packages transformed into a module. As well, activation of a whole lot of small modules could lead to inter-dependency problems hindering deactivation.

[francois]

It thought that the dependencies could be used for future packages needing them at the time of their installation. Even though the original package package could be could be stored in /porteus/optional.

What do you propose?

[Bogomips]

It thought that the dependencies could be used for future packages needing them at the time of their installation. Even though the original package package could be could be stored in /porteus/optional.

What do you propose?

Propose that when default is 'no modules', there should be an option to request a module. This will then be consistent with the present options. As it stands at the moment, if there is more than one package the option to make a module is there, but if there is only one package the option to override the default and make a module is missing. Such an option would be helpful within the procedure being used to resolve non-slackware dependencies.

At present If there is more than one package, in the first USM pass of the procedure one collects them in a subfolder, and in second USM pass the option to merge into one module chosen. Thereafter packages once more downloaded, and then the module made up from these packages has to be separately activated. Further down the line these modules are usually dispensed with, and only their constituent packages are needed to create resultant module bundle.

Proposal

1. Packages should not need to be downloaded more than once. If default is 'no modules', there should be a 'module' option available at the end.
2. And if this option is taken, then packages in subfolder should be used to make module, should subfolder have been requested earlier on.
3. If 'module' option taken, an activation option should then be made available, once module is made.

Present Situation

After selecting merge into module, all other options suppressed, so no go:

Your usm thoughts are far deeper than mine. I like it. I imagine that brokenman has an eye on this thread.
