Suppose I want to set up two hard-disks with RAID 1 (mirroring), is it
possbile ?  I went through the ccd manpage, and it gives an option called
mirroring -- is it the same as what I am asking ?

And another doubt: suppose I use wd0e and wd1e as mirrors -- then, is it
possible that I can access the data of wd0e separately ?  That is, if I
make ccd0 with mirror options using wd0e and wd1e; can I mount wd0e alone
read-only (so that I won't put the mirrors out of sync)  and access the
data in it ?
