I'm getting there. I've got a fairly well minimized kernel that works. -rw-r--r-- 1 root root 4.5M Mar 19 21:21 vmlinuz-3.8.3-lfs-SVN-20130316 -rw-r--r-- 1 root root 5.1M Mar 21 00:46 vmlinuz-test -rw-r--r-- 1 root root 3.1M Mar 21 02:22 vmlinuz-test2 What's really encouraging is the boot time in qemu. The kernel finishes at 1.383953 seconds and the boot scripts take 2 seconds. The network up line from the kernel is the last dmesg entry at 5.072569 seconds. The configuration is really minimal. I eliminated ipv6, netfilter, as many drivers as I thought were unneeded, multiprocessor support, raid, etc. I even reduced the number of loop devices. If I could only reduce the number of ttys, /dev would be quite compact. Searching the net, it seems that would require a change to a header in the kernel. I was thinking about distributing a qemu .img file, but that doesn't seem realistic. The file is now 5.6G (1.5G compressed, but it took almost an hour to do the compression). Adding things like Xorg would just make it bigger. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/lfs-dev FAQ: http://www.linuxfromscratch.org/faq/ Unsubscribe: See the above information page
