I'm sorry, I didn't know that and I didn't want to imply OFW was not the right tool for the job. I'm just very concerned by the current time it takes for a vanilla olpc to be ready, especially when compared to any netbook running moblin, so I'm exploring various ways to fix the problem (actually rereading every documentation that was send to me explaining various aspect of the OFW before starting the UBIFS tests, but I have limited time and I'd like to spend in on the UI rather than on the boot process) What would you suggest to have the kernel loaded in ram as quickly as possible? (I'd guess execute in place, but I think that's not possible) A fat partition with the zimage ? I'd also like to remove the initrd to try to shave some seconds. I don't need any antitheft protection, I just want to protect the nand against a reflash with a non approved software image, which IMHO is the most interesting feature of OFW. But if that's too complicated/requires the initrd or some weird other stuff, I'll scrap that too. BTW, could you point me to some documentation explaining how to have OFW immediately boot a kernel, without fancy sound/screen/counter? (only prioritising USB or MMC, so that it boots first if a media is inserted or if a struck "esc" key is detected it gives a command prompt) I'm open to any additional suggestions. (I'll consider the sysvinit optimisations later) Thanks -- Dr. Guylhem Aznar, MD PhD Unité d'Analyse Médico-Économique Service de Santé Publique et d'Économie de la Santé Pôle SPSSR CHU de Fort de France BP 632 97261 Fort De France Cedex Martinique, France Tel : 05 96 55 23 47 Fax : 05 96 75 84 57 _______________________________________________ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
