The file make.conf contains system-wide settings that will apply to every build using make and the standard sys.mk file. The purpose of make.conf is to control the compilation of the FreeBSD sources, documentation, and ports.
The system build procedures occur in the following areas: the world, the kernel, documentation and ports. Variables set in make.conf may be applicable in one, two, or all four of these areas. In addition, control variables can be specified for a particular build via the -D option of make or in environment.Print This Post
There is way to improve the speed of boot process in Ubuntu Linux by profiling your boot. Profiling lets Ubuntu make a list of all the files that are accessed during bootup, it then sorts the files according to how they are stored on your hard-disk. So the next time the system is booted, the files would be read faster.
To profile boot you need to follow these steps:
- At the grub menu highlight the kernel
- Press e for edit
- Choose the line starting with kernel and press e again. Now add the word profile to the end of this line. Hit Enter and then press b to boot
NOTE: The system will boot slower this one time, the next time however you should see an improvement. Also keep in mind that all this is machine-dependent and also depends on the arrangement of files on your hard-disk, so the difference you see might not be huge, or even nil in some cases.Print This Post
