Over time after doing multiple Kernel updates and security patches. You will notice the /boot partition is getting full to about 90% when doing a df command.

Example
df
/dev/sda34 124427 12078 105925 11% /boot

Is this case I am only using 11% of my boot after cleaning up the unused kernel images.

The Fedora Community has released a Open Source script under the GNU Licensing called Kernel-prune . you can download this script using the following command via ssh

curl -O ‘http://skvidal.fedorapeople.org/misc/kernel-prune.py’

You will then need to make the python script executable by issuing
chmod a+x kernel-prune.py

Then running it using ./kernel-prune.py
The return value will give you a list of unused kernel images which can be safely removed from your system.

To remove the kernels I created a file called cleanboot and added the following content
PKGS=`./kernel-prune.py`
echo $PKGS
yum remove $PKGS

Again making this new file executable using
chmod a+x cleanboot

Then running the file as ./cleanboot

The script will ask you if you would like to remove the unused kernel packages , hit Y for yes and give it a few moments. Perform a reboot and you should be all set.

This script may work on centos and other distros , but i have not tested this solution on those systems. Please make a backup of your data before proceeding with this process.

Thanks,

When trying to enable imagemagick within Gallery2 by Menalto

Check your php,ini file for a directive open_basedir

add the root path that contains the convert binary , so for example if convert is at /usr/bin/convert
set the basedir to
open_basedir = /your/home:/usr/bin

without this settings you will not have access to the /usr/bin folder.

Error
ejabberdctl status
RPC failed on the node ejabberd@localhost: nodedown

This occurred when using a live cd in a virtual player under bridge mode. The app loads after a virtual player reboot, but restarting the service within ssh returned the error. So I did a hard reboot on the host machine which resolve the issue.

You will also need to make sure the host name is correct in the ejabberd cfg file.

error:
Software error: Can’t locate Calendar/CalciumStart.pm in @INC (@INC contains: CalciumDir40/upgrades CalciumDir40/redist …

Solution:
A message like this means that Calcium can’t find its installation directory. The location of the Calcium source code files and data directory are specified in the main Calcium script; some installations will require the full path to the Calcium installation directory here, instead of a relative path. To fix this, edit the main script (Calcium40.pl), and change the line near the top that looks like this:
BEGIN {$Defines::calendar_root = ‘CalciumDir40′}
Replace CalciumDir40 with the full filesystem path to that directory. For example, something like:
BEGIN {$Defines::calendar_root = ‘C:\public\html\cgi-bin\CalciumDir40′}
or maybe
BEGIN {$Defines::calendar_root = ‘/usr/local/apache/cgi-bin/CalciumDir40′}
should help.
