Do you know if it is possible to switch the scheduler at runtime?

echo cfq > /sys/block/<disk>/queue/scheduler


At least one can do a ls of the /sys/block area & then do an automated echo cfq down the tree . Does anyone know of a method to set a default scheduler ? Scanning down a list or manually maintaining a list seems
    to be a bug in the waiting .  Tia ,  JimL

Thought I posted this... it can be set in kernel build or on the bloot parameters from grub/lilo.

2nd thought: set it to cfq by default, then at the END of rc.local, if there are no arrays rebuilding, change to something else if you like.
