[indiana-discuss] Default Partitions sizes

[Sanjay Nadkarni]

This will be a non-issue for Indiana. Our plan for the first prototype 
release in October is assign the entire fdisk partition  to a zfs pool. 
It will be set up as a mirrored pool.  A user will have to add the 
second disk. There will be datasets for /usr, /opt, /export, etc.   Swap 
will be on a zvol.    I would love to have feedback on this.

So it will look something like this:

<indiana-build> zpool status                                     
  pool: mypool
  state: ONLINE
  scrub: scrub completed with 0 errors on Wed Sep 26 23:41:40 2007
  config:

         NAME          STATE     READ WRITE CKSUM
         mypool        ONLINE       0     0     0
           mirror      ONLINE       0     0     0
             c3t0d0s0  ONLINE       0     0     0

errors: No known data errors

BTW, all UFS file system on Nevada have logging on by default.   For ZFS 
journaling is not required

We no longer need to worry about running out of disk space and having to install programs in other directories only to find out that they sometimes don't behave properly if they aren't installed in their "default" directory (usually /usr/local or /opt)
