With the release of Core 4.2 which adds a lot of new features (the biggest being modularity), I figured I'd take another shot at this. I recompiled the latest 3.0.x kernel, which is 3.0.9 and applied all the TC patches. I also built and copied over all the modules from 3.0.9 that TC 4.2 (kernel 3.0.3) uses. This all boots up just fine. Upon doing this, I realized that cifs is not even a module in the default TC initrd. When I built the 3.0.9 modules, I saw the cifs module in /kernel/fs/cifs but TC does not use it (only modules in /kernel/fs are fat, ntfs, and squashfs). Therefore, is this problem not kernel related but extension? Or am I missing something? Also, with me running 3.0.9, are the 3.0.3 extensions like filesystems-3.0.3-tinycore.tcz compatible? I would assume not.
