It's copied from the main system when the initramfs is created, unless it's faulty or doesn't represent the system or hasn't been checked since the 2.5.3 upgrade. In the initramfs, if there is a config file, it's used. If there's not a config file, mdadm scans all partitions and assembles them all (like /sbin/mdadm-startall). Thus, if you remove it in the initramfs, you basically tell the system that you want it to scan, rather than search for the specific UUID in the file. > Perhaps if I could figure out how to grab the dmesg output from > initramfs environment, I could then compare the amd64 kernel > output to the 686-bigmem kernel output... :-/ Append 'break=bottom debug' to the kernel line and at the shell do something like mount -o remount,rw /root cp /dev/.initramfs/initramfs.debug /root/root/initramfs-debug.foo mount -o remount,ro /root and then find the file in /root once the system booted. -- .''`. martin f. krafft <madd...@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems review of a chemistry paper: "paper should be greatly reduced or completely oxidized." -- frank vastola
