converting running system to RAID-1

[Jack Howarth]

    I have found the following write-up for converting a running system
to RAID-1...

http://wiki.archlinux.org/index.php/Convert_a_devfs_single_drive_system_to_RAID

The description is for a Sun workstation so it uses cfdisk instead of sfdisk.
However other than making that change does the procedure look likely to
work under Fedora? Thanks in advance for any advice.
