How To Cut Your Linux PC’s Boot Time in Half With E4rat

Filed under

Linux is pretty quick to boot on modern computers, but why not pare it down some more? If you’re hurting from a lack of SSD or just want to boot faster, E4rat will easily shave down your boot time.

E4rat and Your Linux PC

E4rat is a utility that’s designed to cut your Linux boot time drastically. Essentially you show it what you do when you start your computer normally, and it analyzes the files you access and use. Then, it’ll move them to the beginning of your hard disk so that it takes less time to find them during boot.

E4rat is designed to work with Ext4 partitions only. If you’re using another file system, this isn’t for you. There are reports of it working with LVM but your mileage may vary, so be careful if you have sensitive data.

Leftovers: FSF/GNU

  • I support Software Freedom Conservancy
    Conservancy provides a lot of services to member projects, including financial and administrivia. Conservancy also provides license enforcement services, including support of a high-profile suit against VMWare. Although Conservancy uses litigation as a last resort, it’s sometimes necessary. However, this has lead to some corporate sponsors pulling their funding.

  • FSF to begin accepting GPG signatures for copyright assignments from Italy
    The Free Software Foundation is striving to provide more and simpler ways for hackers to contribute to the GNU Project. For projects that are assigned to the FSF (such as GNU Emacs or GCC), dealing with the paperwork for assigning contributions can sometimes be a bottleneck in the process. We are always working on ways to make assignment itself simpler. We have accepted GPG-signed documents from U.S. contributors for some time now. Our legal counsel at the Software Freedom Law Center recently gave us the all clear to begin accepting GPG and electronic signatures from contributors in Italy. We would also like to thank Carlo Piana for providing local counsel on this issue as well.
  • It's Fall, still, and the Bulletin is out!
    As many of you are aware, twice a year we mail a new edition of the FSF Bulletin to our members and supporters via the good old United States Postal Service. The Bulletin comes together in just a few weeks, and this time we had to make an extra quick turnaround after celebrating FSF30.
