Yes, but rsync and cron are there to help.

In any case, I just realized it's not only initramdisk that
has to to understand and use software raid, but even
before that there's grub (or lilo.. anybody out there still use lilo 
nodays?).. I suppose even legacy grub can boot from raid partition
otherwise, CentOS4's grub would not even boot.

But as already many on this list say it's better to have even
boot and swap on raid, then I'll try that way.

I hope that will give me two drives partitioned in exactly
the same way. This would be to me the greatest gain over
my solution.

Thank you very much to you all for your help.
Best regards.
