Hi BSD'ers !

I'm in need of some help or suggestions regarding a setup
with FreeBSD on a machine with two IDE disks.

I want to run RAID-1 on those disks, and I'm pretty sure I
can do that with Vinum. However, it's not clear to me whether
I can make the system boot on the logical RAID-1 volume.

Is it possible ?   How ?

The Vinum docs say it's not recommended to have Vinum directly
in the kernel (it should instead be a loadable module). Now, I
would expect that this means that I cannot boot on a Vinum 
volume.  Why isn't it recommended ?


I have a final question with which I do not intend to start
a flame war...  How can I expect FreeBSD disk I/O performance
to compare to Linux disk I/O performance ?  Especially with
regards to stat() and fsync() ?  (I will be running a mail-server
with ./Maildir/ support)

Thank you for your time,
