Agreed.

I prefer > moddb.lrp. I don't like the idea of a parameter because it adds complexity. The implementation in 5.2 will be pretty straightforward even for small, but nowadays common boxes with more than 32MB of storage. To support still smaller/older systems (or to speedup boot) adding code to save and use moddb is all I'm asking for. If we move on carefully, nothing will change for older/smaller boxes. > IMHO it should be > > - load kernel and an absolute minimum of device drivers for the > architecture, I _believe_ initmod is overcharged. > - load drivers as defined in moddb and /etc/modules > - if modules.sqfs exists, use it to load additional modules > - _don't_ touch the modules backup logic in any case kp ------------------------------------------------------------------------------ _______________________________________________ leaf-devel mailing list leaf-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/leaf-devel
