I have been using a some proven steps to create my own Oracle Linux 6uX ISO images with a custom kickstart script for a long time. What i basically do is mount the iso-image using hdiutil, copy the contents to a working folder, make the modifications and create an iso using makeiso (cdrutils).
Details have been described here; http://www.reddipped.com/2015/12/virtualbox-soa-bpm-osb-bam-33-minutes/
I just made my first attempts to create a custom Oracle Linux 7u2 ISO images, but miserably failed till now.
First opening the image using hdiutil gives and 'hdiutil: attach failed - no mountable file systems'. Instead i used Keka to extract the contents of the iso.
Modified the contents of the extracted iso-image;
Removing /isolinux/boot.cat,
Adding a new ks-bd.ks
Adding a menu item to the isolinux.cfg to be able to start installation using the kickstart file
label linux_basicserver_silent\
menu label ^Install basic server silent\
menu default\
kernel vmlinuz\
append initrd=initrd.img ks=cdrom:\/ks-bd.ks\
Then created an iso again;
## Make isolinux.bin writable
chmod u+w V100082-01U/isolinux/isolinux.bin
# Build the V100082-01Uiso
cdrtools/cdrtools-*/mkisofs/OBJ/i386-darwin-clang/mkisofs -r -J -T -o V100082-01U.iso -b isolinux/isolinux.bin \
-c isolinux/boot.cat -no-emul-boot -boot-load-size 4 -boot-info-table -R \
-m TRANS.TBL -v -V Oracle\ Linux\ 7.2 ./V100082-01U
After mounting the iso image and selecting the 'linux_basicserver_silent' installation option the installation seems to stall on the message 'Starting automated install'
When selecting a standard interactive installation in the installation menu the installation also freezes with the latest step 'Reached target Basic System'
After some minutes the same error 'dracut-initqueue timeout' is repeatedly shown .
Any hints how to fix this?
-- Update 10/27/2016 --
When comparing the orignal iso with the created iso using mkisofs there are no substantial differences, i think..

Instead of using 7zip, use the cdrtool utility isoinfo to extract the original iso image.
mkdir V100082-01U
cd V100082-01U
isoinfo -R -X -i ../V100082-01.iso
Then modify the image and rebuild using mkisofs
## Make isolinux.bin writable
chmod u+w work/isolinux/isolinux.bin

I have a two-page PDF I'm trying to convert to a PNG file. When I run:
gs -sDevice=pngalpha -o=gs-output-%d.png -r400 test1-0.pdf
I get:

And then... nothing. No output files at all. Where am I going wrong?
You're so close you'll be mad ;-)
After a bit of manpage reading here's what worked for me:
gs -sDEVICE=pngalpha -ogs-output-%d.png -r400 test1-0.pdf
i.e. DEVICE instead of Device, and -o instead of -o=
In case it matters, my gs version is:
GPL Ghostscript 9.05 (2012-02-08)
try this which works perfectly with me and it get a very good results:
-sDEVICE=pngalpha -o "$OUTPUTIMAGEFILE" -dFirstPage=1 -dLastPage=2 -dNOPAUSE -dGraphicsAlphaBits=4 -dTextAlphaBits=4 "$INPUTPDFFILE"
However i guess that using -r400 is for JPEG images not PNGS
just installed pocketsphinx on my raspberry pi. Think i'm going crazy but not sure if I'm providing the correct device.

I'm using a ps3eye currently. If i do a simple:
arecord -D plughw:1,0 -d 5 -q -f cd -t wav ~/test.wav
Everything works fine ( Verified this by hooking up Raspberrypi to TV via HDMI and running aplay ~/test.wav )
What am I doing wrong guys?

apt-get remove pulseaudio -y
aptitude purge pulseaudio -y
# sphinxbase install
apt-get install bison -y
cd /usr/install

Took me a while, with with some help from a couple sources ( they will be listed in my answer ) and some helpful hints from nikolay-shmyrev, I finally came up with an answer that worked for me.
Key assumptions:
running these commands as the pi user ( previously I was running them as root, which was incorrect )
I'm using continuous recognition and I was ONLY looking for the ability to "wake-up" my raspberry pi. Upon waking it up, I have other plans on how it should interact.
My setup:
Canakit RaspberryPi
HDMI cable to my Toshiba TV
usb wifi dongle
Playstation 3 Eye for speech recognition
Moving forward. I ran the following commands on my RaspberryPi to get PulseAudio + pocketsphinx working together w/ my Playstation 3 Eye. ( If you see any places for improvement please let me know )

I plan on adding more details behind why I used certain setting, configurations in a blog post i'm writing on my home automation project, but figured, i'd share what i've done thus far incase someone else was stuck like me and would like to move forward with what they're working on. Hope this helps someone. Thanks for the advice guys.
apt-get remove pulseaudio -y
aptitude purge pulseaudio -y
If you don't know how to configure alsa, you should better use pulseaudio, moreover, it's configured on your system. You should better compile sphinxbase with pulseaudio support. For more information read the FAQ:
http://cmusphinx.sourceforge.net/wiki/faq#qfailed_to_open_audio_device_dev_dsp_no_such_file_or_directory
Mixer load failed: Invalid argument
This is a key message, it says that your alsa configuration doesn't support level mixer. If you don't know how to add mixer in alsa configuration, use pulseaudio
./configure --enable-fixed
This is a bad idea too which will reduce both speed and accuracy on your device. Your processor has FPU, so you shouldn't use fixed point mode.
i had the same problem of failing to open audio device.

I fix it buy installing libpulse-dev package then reinstall sphinxbase , pocketsphinx.
I am trying to work more efficiant with sparse files. I have read about the SEEK_HOLE functionallity in newer Linux Kernels. According to other people, this should be in Kernel version 3.1 and later.
However, as seen bellow, there must be something else to it as well.
I am on kernel 3.2+ and working with sparse files are still slow.
Doing a "cp" or "tar" on this (completely empty) sparse file should take less than 1 sec.
Any idea what I am missing? How can I check if SEEK_HOLE is supported/activated?
They discuss the same thing here, but for some reason I cannot post comments there that it does not work:

Make sure you are using a tool that supports SEEK_HOLE.
bsdtar >=3.0.4
cp >=8.13
Also make sure you run a filesystem that supports it. Works fine with ext4. Does not work with reiserfs.
Facing a peculiar problem when doing load testing on my laptop with 2000 comcurrent users using cometd. Following all steps in http://cometd.org/documentation/2.x/howtos/loadtesting.
These tests run fine for about 1000 concurrent client.
But when I increase the load to about 2000 CCUs, the terminal just shuts down.
Any idea what's happening here?
BTW, i have followed all the OS level settings as per the site. i.e.
# ulimit -n 65536
# ifconfig eth0 txqueuelen 8192 # replace eth0 with the ethernet interface you are using
# /sbin/sysctl -w net.core.somaxconn=4096
# /sbin/sysctl -w net.core.netdev_max_backlog=16384
# /sbin/sysctl -w net.core.rmem_max=16777216
# /sbin/sysctl -w net.core.wmem_max=16777216
# /sbin/sysctl -w net.ipv4.tcp_max_syn_backlog=8192
# /sbin/sysctl -w net.ipv4.tcp_syncookies=1
Also, I have noticed this happened even when I run load tests for other platforms. I know this has to be something related to the OS, but I cannot figure out what it could be.
ulimit command has been executed correctly? I read something about it in Ubuntu forum archive and Ubuntu apache problem.
