Re: How to use blfs-tool and BLFS

Now I trying to do the next step: using blf-tools and BLFS. But I think, I did not understand the idea behind these tools. To build LFS with blfs-tool support seems not enough. After reboot, installing of BLFS packages fails because some system tools like sudo etc. are not installed. Have I to install needed tool manually? Before reboot? Should I build BLFS packages before reboot, directly after building LFS? What is the right path? Thanks a lot. Heinrich Bearing in mind that the whole idea behind LFS is to educate people in building and using Linux, it's a pity that the documentation for the jhalfs tool, like nalfs before it, is so poor. However the lead developer's first language is not English, so he can be forgiven (and even the original developer was American ;-). You'll need to look at the actual scripts to understand how they work Heinrich. Then, once you've worked it all out, write us a jhalfs howto :-) As Randy says, they are not newbie tools. But as I once said to my programmers: a program without user documentation is not a program at all. But I was paying them, and no one pays the jhalfs team! BLFS is a 'dip in and build the bits you want' book, the blfs-tool is more a: dependency management tool with a package builder on the back, than a blfs automated machine. Its job is to examine the blfs book and build a set of scripts to build the dependencies of the target as well as the target itself. You then have to edit the scripts to make something useful. It isn't an automated build system, like, say, portage. Best of luck, R. The documentation is really poor, but it seems to be enough. I tried the whole procedure from scratch :) and … it works. Now, using LFS + jhalfs, BLFS with blfs_tool and my own tools, I am able to build a completely new system in 2 to 4 hours, depending on how much time I spend to the kernel configuration and how many BLFS packages should be compiled. The procedure is not fully automated, but it is what I am looking for – a defined bundle of commands. I will try to write down my results later. Many thanks to everyone, especially to the xLFS Team for the great job Heinrich -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page

If it doesn't exist yet, run this command: echo quit | grub --batch --device-map=/boot/grub/device.map -- Dan -- http://linuxfromscratch.org/mailman/listinfo/blfs-support FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
