Arch Linux

Description: Using the archlinux-2010.05-core-dual.iso or archlinux-2010.05-netinstall-dual.iso to install arch. In the section "Set Filesystem Mountpoints" the menu only displays the device names without any further information. Because of the way udev works this makes it impossible for me to identify the partitions by device name.

I'm guessing that I'm supposed to remember the device name from the "Partition Hard Drives" section. This would be fine, however cfdisk is unable to read my partitions because they are labelled in reverse order. I get the following error:

FATAL ERROR: Bad primary partition 0: Partition ends in the final partial cylinder.

fdisk -l yields:

Partition table entries are not in disk order
[/code]

In human readable terms I have 3 primary partitions (for two linux systems and a swap space) and one extended with two virtual partitions (for different data).

Reading around people suggest that the only solution is to format the hard drive and start again. This isn't possible for me. It also seems excessive when other programs such as gparted\parted don't complain about the partition order.

Some additional information other than just the device name would be helpful. In particular the partition size. I don't know if it normally does display the size but it fails to for the same reason as cfdisk fails.

I don't want to blindly pick a device name for the partition as I don't want to lose my data. As such, I'm unable to proceed with the installation.

Steps to reproduce:
1) Have a partition table listed in reverse order.
2) Try sections "Partition Hard Drives" and "Set Filesystem Mountpoints"
