Hi, I am in the progress of updating the toolchain and thought it time to review what our minimum required kernel version is for glibc. For those that do not know, assuming a newer kernel allows glibc to have less workarounds compiled in. So it may be advantagous to have a more recent version as the minimum required. This comes at the obvious cost of not having support for older kernels so a tradeoff is needed... When we discussed this 18 months ago, it was decided 2.6.18 was appropraite then, but much has changed since. I am going to suggest that we follow the oldest longterm support kernel. That would now be the 2.6.27.x series, which has been around for over two years. That might be being overly bold, so feel free to point out how much such an update would break... and suggest an alternative minimum. Allan
