The proc file system is the process -information pseudo file system through which the kernel provides information -about the status of the system. And the devpts file system is nowadays the most -common way pseudo terminals (PTYs) are implemented. Since kernel version 2.4, a -file system can be mounted as many times and in as many places as you like, -thus it's not a problem that these file systems are already mounted on your -host system, especially so because they are virtual file systems.</para> - -<para>First become <emphasis>root</emphasis>, as only <emphasis>root</emphasis> -can mount file systems in unusual places. Then check again that the LFS -environment variable is set correctly by running <userinput>echo -$LFS</userinput> and making sure it shows the path to your LFS partition's -mount point, which is <filename class="directory">/mnt/lfs</filename> if you -followed our example.</para> - -<para>Now make the mount points for these filesystems:</para> - -<screen><userinput>mkdir -p $LFS/{proc,dev/pts}</userinput></screen> - -<para>Mount the <emphasis>proc</emphasis> file system with:</para> - -<screen><userinput>mount proc $LFS/proc -t proc</userinput></screen> - -<para>And mount the <emphasis>devpts</emphasis> file system with:</para> - -<screen><userinput>mount devpts $LFS/dev/pts -t devpts</userinput></screen> - -<para>This last command might fail with an error like:</para> - -<blockquote><screen>filesystem devpts not supported by kernel</screen></blockquote> - -<para>The most likely cause for this is that your host system's kernel was -compiled without support for the devpts file system. You can check which file -systems your kernel supports by peeking into its internals with -<command>cat /proc/filesystems</command>. If a file system type named -<emphasis>devfs</emphasis> is listed there, then we'll be able to work around -the problem by mounting the host's devfs file system on top of the new -<filename>/dev</filename> structure which we'll create later on in the section -on <xref linkend="ch-system-MAKEDEV"/>. If devfs was not listed, do not worry -because there is yet a third way to get PTYs working inside the chroot -environment. We'll cover this shortly in the aforementioned -<xref linkend="ch-system-MAKEDEV"/> section.</para> - -<para>Remember that if for any reason you stop working on your LFS, and start -again later, it's important to check that these file systems are mounted again -before entering the chroot environment, otherwise problems could occur.</para> - -</sect1> - |
