Well, "best" depends on your goal. The design of yaird is to create "working ramdisks only", based on your current hardware - it refuses to build ramdisks suspectedly not working (eg. when upgrading kernel and the new kernel lack a required driver). As Max indirectly suggest, you could also switch from yaird to initramfs-tools, the alternative ramdisk generator he is maintaining. The design of initramfs-tools is to create "general mostly working ramdisks", inspired by your current hardware - it relies on udev to figure out the hardware needed. > What are advantages for using generic-kernles if they always fail > after hrdware upgrade? None of the ramdisk generators in Debian do *always* fail after hardware upgrade. If you want plug'n'pray where you usually don't need to plan ahead, then use inintramfs-tools. If you like the yaird design goal, then you need to prepare when switching your setup: Each ramdisk image is optimized for a specific setup, so you need to somehow generate an image _after_ changing setup but _before_ booting into it. If all you need is to load that different driver, then edit /etc/yaird/Default.conf and add "MODULE sta_via" and regenerate. But if your rootfs is not virtualized (through raid, lvm or other means) it probably changes as well (from /dev/hdXX to /dev/sdXX) and you need to boot the new hardware setup through an external media (debian-installer testing images should do), chroot into your system and regenerate. Leaving this bug open, as it is uncertain if yaird completely fails to detect this VIA-based hardware correctly... - Jonas -- * Jonas Smedegaard - idealist og Internet-arkitekt * Tlf.: +45 40843136 Website: http://dr.jones.dk/ - Enden er nær: http://www.shibumi.org/eoti.htm
