The mdadm experimental package offers this via debconf (default off for now). I would appreciate testers — I literally whacked this up on a rainy Sunday with an hangover, and while it seems to work fine, it's probably got warts. If you don't run Debian or a derivative, you can get the files from debian/initramfs/* in git://git.debian.org/pkg-mdadm/mdadm.git or http://git.debian.org/?p=pkg-mdadm/mdadm.git;a=tree;f=debian/initramfs;hb=HEAD don't be scared off by the complexity, incremental assembly actually bypasses most of the (shell) code in both scripts. > Yes, you could make the in-kernel autodetection smarter so it > doesn't have to wait quite so long, but that would make it quite > a bit more complex, and it is harder to maintain the complexity in > the kernel. It is definitely a user-space task, if you ask me. -- martin | http://madduck.net/ | http://two.sentenc.es/ windows 2000: designed for the internet. the internet: designed for unix. spamtraps: madduck.bogus@xxxxxxxxxxx
