zdev.conf entries

[robsee]

Hi,

On Ubuntu I'm running into problems where my drive identifiers /dev/
sdx are changing every so often when I reboot (the esata arrays I'm
using take a while to come up correctly.) When this happens I have to
export and re-import the pool to make it see all the devices. Looking
through the code I see that along with being able to put by-path
entries into the file, I can also use by-id. What I am wondering is
what is the best way to make it so that the zfs metadata points to the
by-id entry rather than the /dev/sdx entry.

Thanks,
-Rob
