Booting Linux faster

Dokeun Lee, Youjip Won

Robust Linux memory acquisition with minimal target impact

Johannes Stüttgen, Michael Cohen
2014 Digital Investigation. The International Journal of Digital Forensics and Incident Response  
On Linux, kernel modules must be compiled against the exact version of kernel headers and the exact kernel configuration used to build the currently executing kernel.  ...  This makes Linux memory acquisition significantly more complex in practice, than on other platforms due to the number of variations of kernel versions and configurations, especially when responding to  ...  Acknowledgments We would like to thank Darren Bilby and Heather Adkins for reading a previous version of this paper and giving us valuable feedback and suggestions for improvement.  ...
