I use a Software RAID0 for data
And on this software-raid-volume, there are my MySQL-Databases, /home and other stuff that should be fast…
And, like all volumes, this software-raid-volume is mounted during boot-time.
But since my /home is also on that volume, it should be mounted using a bind-mount.
So first there is a mount using a mdadm: /dev/md127 -> /mnt/data,
And second there is a mount using bind-mount /mnt/data/home -> /home

It took me quite a while to figure out how to get this done at boot-time, but I managed!
Here’s what my /etc/fstab looks like:

# /etc/fstab: static file system information.
#
# noatime turns off atimes for increased performance (atimes normally aren't
# needed; notail increases performance of ReiserFS (at the expense of storage
# efficiency).  It's safe to drop the noatime options if you want and to
# switch between notail / tail freely.
#
# The root filesystem should have a pass number of either 0 or 1.
# All other filesystems should have a pass number of 0 or greater than 1.
#
# See the manpage fstab(5) for more information.

# <fs>            <mountpoint>    <type>        <opts>        <dump/pass>

# NOTE: If your BOOT partition is ReiserFS, add the notail option to opts.
LABEL=boot        /boot        ext2        noauto        1 2
#/dev/sda3        /boot        ext2        noauto        1 2


LABEL=root        /        ext3        defaults    0 1
#/dev/sda4        /        ext3        noatime        0 1

# DATA
LABEL=data        /mnt/data    ext3        defaults    0 1

# HOME (bindmount)
/mnt/data/home         /home        bind        defaults,bind    0 0

# SWAP like RAID0. The higher the value the higher the priority. (max=32767)
/dev/sda5        none        swap        sw,pri=1    0 0
/dev/sdb5        none        swap        sw.pri=1    0 0

#/dev/fd0        /mnt/floppy    auto        noauto        0 0

# glibc 2.2 and above expects tmpfs to be mounted at /dev/shm for
# POSIX shared memory (shm_open, shm_unlink).
# (tmpfs is a dynamically expandable/shrinkable ramdisk, and will
#  use almost no memory if not populated with files)
shm            /dev/shm    tmpfs        nodev,nosuid,noexec    0 0
proc            /proc        proc        defaults        0 0

For the attentive readers:
Yes, I did put my boot on a separate partition. And getting this done on a PowerMac G5 is quite an exhibition! Maybe someday, someday I’m gonna blog about that too!

Apparently the portage-tree doesn’t contain SABnzbd. Too bad! I really needed some binary newsgroup downloader. And I did have some experience with running it on my local machine, a MacPro. Wonderful App! Or tool, or server, or whatever…

But there I was, left alone, helpless and disillusioned…
What to do now?

Well, basically…… This!
(keep in mind, I’m using a PPC64)

Installing
Edit /etc/portage/package.keywords, and add:
# SABnzbd
dev-python/* **
app-arch/par2cmdline *

And now run (not specifically in this order):

# emerge dev-python/pysqlite
# emerge dev-python/cheetah
# emerge dev-python/pyopenssl
# emerge sqlite
# emerge par2cmdline
# emerge unrar

Download the SABnzbd-sources:

# wget http://sourceforge.net/projects/sabnzbdplus/files/sabnzbdplus/sabnzbd-0.5.6/SABnzbd-0.5.6-src.tar.gz

Unzip/Unpack SABnzbd.zip to an appropriate directory,
cd into newly made directory,
Edit /.sabnzbd/sabnzbd.ini, and change the host-value ‘localhost’ to 0.0.0.0,
Now run SABnzbd.py and you can configure the rest of SABnzdb using your browser, (Ahhhhh….)

# ./SABnzbd.py


Security
Although this post isn’t about security, be aware that in this particular example SABnzbd is now running as root. And that ain’t necessary at all!

It is possible, and advised by me ;-), to create a sabnzbd-user, and let it run under that newly created sabnzbd-account.
Naturally, you have to do some chowning to the SABnzbd-directory. (Also to the .-directories which are ignored by default by chown!)

Fun stuff
Further more a tip for extra fun and carefree usage:
Create a SABnznbd-writeable directory /var/log/sabnzdb,
In the sabnzbd.ini in the ./sabnzbd-dir: Change the logdir (logs) to /var/log/sabnzbd

You are maybe asking yourself: “What’s the fun of that?”
Well, just take a look at xtail.pl, and you’ll find out!
