[SOLVED] Installation with august cd changes harddisk order.

Good evening,
wanted to do a second Arch install with the live medium from August.
With the following command

mkfs.ext4 /dev/sdb6

I got the error that /dev/sdb6 did not exist.
Using 'blkid' showed my harddisks in another order as normal; the first harddisk had switched to third place.
I tried some other Arch install CD's, who all gave me the correct order of the harddisks, finally did the install
with the June-CD.
Is this something that can be categorized as a bug?

EDIT: changed the subjec title to be able to add [solved]

Re: [SOLVED] Installation with august cd changes harddisk order.

I think that proper way to find the order is by searcching using uuid because it won't change after boot, with naming as /dev/sdXY, for an exmaple, on my desktop, each boot live cd with various linux distrubtion results with different hard disk order.

Re: [SOLVED] Installation with august cd changes harddisk order.

Label option works as well. Check out tune2fs man page to show you have to label . Then update accordingly in /etc/fstab  :

# 
# /etc/fstab: static file system information
#
# <file system>	<dir>	<type>	<options>	<dump>	<pass>
tmpfs		/tmp	tmpfs	nodev,nosuid,mode=1777,size=4G	0	0

# OCZ : SSD -- /dev/sda
LABEL="Arch" 	/	ext4	defaults,discard	0	1 
#LABEL="Home" 	/home	ext4	defaults	0	1

Re: [SOLVED] Installation with august cd changes harddisk order.

Let me try to explain this way

# blkid

This is shown to me using the Arch cd's from December, January, February,April, June plus my existing Arch install.
When I use the cd from August I get

# blkid

Nothing has changed as of wiring or in the BIOS. I have several other distro's installed, hence the
number of partitions on sdb; they all installed giving the correct HHD order.
I just thought it to be a bit weird that using one particular cd gave a different order.

It's a different kernel, so it's not really "weird" that things happen differently. The sdX designations have always been a bit random.

And this is why you should use filesystem labels... or UUIDs.

Fair enough. Marking this as solved; it wasn't really a problem to begin with, just an observation.
