But the Linux kernel source tree is often kept 15 around for a long time, so there's a chance whatever userid was used will16 be assigned to somebody on your machine , and that person would getwrite17 around for a long time, so there's a chance that whatever userid was used will 18 be assigned to somebody on your machine and that person would have write 17 19 access to the kernel source.</para> 18 20 19 21 <para>In light of this, you might want to run <userinput>chown 20 0.0</userinput> on the linux-&kernel-version; directory to ensure all files21 are owned by user <emphasis>root</emphasis>.</para>22 0.0</userinput> on the <filename>linux-&kernel-version;</filename> directory 23 to ensure all files are owned by user <emphasis>root</emphasis>.</para> 22 24 23 <para>The kernel headers are installed by running the following 24 commands:</para> 25 <para>Kernel header installation requires the <emphasis>pwd</emphasis> program. 26 In the kernel source, the path to the pwd program is hard-wired as /bin/pwd. 27 Create a symlink to account for that:</para> 25 28 26 <para><screen><userinput>ln -s /static/bin/pwd /bin/pwd && 27 make mrproper && 28 make include/linux/version.h && 29 make symlinks && 30 cp -HR include/asm /usr/include && 31 cp -R include/asm-generic /usr/include && 32 cp -R include/linux /usr/include && 33 touch /usr/include/linux/autoconf.h && 34 rm /bin/pwd</userinput></screen></para> 29 <para><screen><userinput>ln -s /static/bin/pwd /bin/pwd &&</userinput></screen></para> 30 31 <para>Prepare for header installation:</para> 32 33 <para><screen><userinput>make mrproper</userinput></screen></para> 34 35 <para>This ensures that the kernel tree is absolutely clean.
