Comment 1 for bug 573477

I spotted this error while installing lucid lynx and mdadm on another machine:

Setting up mdadm (2.6.7.1-1ubuntu15) ...
Generating array device nodes... /var/lib/dpkg/info/mdadm.postinst: 170: /dev/MAKEDEV: not found
failed.
Generating mdadm.conf... done.
 Removing any system startup links for /etc/init.d/mdadm-raid ...

Could this have something to do with the array not starting?

Here is the complete transcript of the install:

Postfix is now set up with a default configuration. If you need to make
changes, edit
/etc/postfix/main.cf (and others) as needed. To view Postfix configuration
values, see postconf(1).

After modifying main.cf, be sure to run '/etc/init.d/postfix reload'.
