Thanks, I didn't realize I didn't 'reply-all' to stay on the list.

Hopefully it will snowball as people who use it then contribute back
<hint> ;)

I will, I'm also keeping notes and changes to the man page. :)

--auto md

Ah. Thanks for the example(s).

quoted

Also, when I use "--create /dev/nicename --auto=p1" (for example), I
also see /dev/md_d126 created.  Why?  There is then a /sys/block/md_d126
entry (presumably created by the md driver), but no /sys/block/nicename
entry.  Why?

Not sure who creates this, mdadm or udev

I'm guessing the kernel's md driver creates it; neither mdmadm nor udev
(just as the kernel creates, for example, sd* disk entries in /sys, but
udev creates the nice entries in /dev).

The code isn't that hard to read and you sound like you'd follow it if
you fancied a skim-read...

I read it for the --create option to see who created /dev/mdXX. :) I'll
take another look.

Thanks David.

Cheers.
