Re: ZFS on root - almost there

[Chavdar Ivanov <ci4ic4%gmail.com@localhost>]

I just noticed - the error message from the sysctl command was that
the string was too long:

# sysctl -w kern.module.path=/a/stand/amd64/9.99.47/modules
sysctl: /a/stand/amd64/9.99.47/modules: string too long

I tried with the shortest possible substitution.
