Guennadi, since you seem to be the one responsible for the linkstation/kurobox in the kernel, I would like to ask you a few things that I couldn't quite understand. Please, forgive my ignorance here while I ask you some things: - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - 01. why is anticipatory the default scheduler for linkstations when CFQ is the default scheduler for the rest of the kernel? 02. since kuroboxes/linkstations are meant to store files, is there any reason why they don't have support for large blk devs enabled by default? 03. why is CONFIG_MIGRATION enabled in such low memory devices? 04. why is CONFIG_BLK_DEV_RAM enabled by default? 05. why is SCSI_LOWLEVEL enabled, if no device under that tree is used? 06. idem for CONFIG_NETDEV_10000. 07. idem for CONFIG_WIRELESS. 08. idem for CONFIG_HWMON. 09. idem for CONFIG_CRYPTO_HW. 10. any reason why CONFIG_VIDEO_OUTPUT_CONTROL is configured as a module? 11. any reason why CIFS is not configured with extended attributes, while both ext3 and nfs are? 12. wouldn't it be a good thing to enable CONFIG_PRINTK_TIME? - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Perhaps similar remarks would apply to the other device that you maintain? I forgot its name. Again, please, forgive my ignorance here regarding the questions above. I'm really looking for some clarification and to get things in shape both on my systems and in the default kernel configuration, in general. Thank you very much for your contributions, Rogério Brito. -- Rogério Brito : rbrito@{mackenzie,ime.usp}.br : GPG key 1024D/7C2CAEB8 http://www.ime.usp.br/~rbrito : http://meusite.mackenzie.com.br/rbrito Projects: algorithms.berlios.de : lame.sf.net : vrms.alioth.debian.org
