On the subject of disabling kernel module loading on SunOS 4.1.x: several people asked me what the side effects of this might be. I researched it; and the answer appears to be that what the user gives up, so far as supported vendor software, is the ability to run OpenWindows with the "-nosunview" option. That is, if you disable loadmodule, or modload, or the loading of modules, the kernel will not be able to load keyboard and mouse drivers on the fly that the server usually relies on the sunview code to supply.
I don't understand this, perhaps because I'm not an OpenWindows user. Are you saying that a subset of OpenWindows requires dynamic device driver support, but the whole of it doesn't? The real question is: can you link these drivers in in a permanent fashion when you build your 4.1.X kernel, and then disable all dynamic loading and unloading, or does the act of loading/unloading these particular drivers have an active side-effect that means you can't do this? -- Jeff Smith, Computer Science, Warwick University, Coventry, CV4 7AL, England jeff () dcs warwick ac uk phone: +44 203 523485 fax: +44 203 525714
