Devtmpfs got added 7 years ago (2.6.32) - And is easy to backport if really needed, is easier and more flexible than a bunch of static mknods, and probably smaller as well. We changed to devtmpfs by default in Buildroot quite some time ago, and I'm pretty happy with it. -- Venlig hilsen, Peter Korsgaard _______________________________________________ linux-snps-arc mailing list linux-snps-arc@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-snps-arc
