unfortunately not. This is an area where some work should be invested. It would require to do things properly in order also. LVM support also comes to mind. I think these devices can be staged in an arbitrarily complex way, no? Encrypting a RAID device, or creating a RAID device from encrypted partitions, for instance (of which the former sounds more reasonable to me). > I understand that in Linux, the device file names (e.g., /dev/sda3) can > sometimes change unexpectedly.

But I have never experienced this kind of problem for hard disks. > Does the code in this gexp get invoked every time the system starts up? > Why is a loop better here than an error? Yes. An error is too harsh: When I tried things out, my RAID assembling was (tried to be) carried out before the hard disks were visible, so this failed. Waiting a little solved the problem. Andreas
