<title>Mounting Virtual Kernel File Systems</title>
<para>Various file systems exported by the kernel are used to communicate to and
from the kernel itself. These file systems are virtual in that no disk space is
used for them. The content of the file systems resides in memory.</para>
<para>Begin by creating directories onto which the file systems will be
mounted:</para>
<screen><userinput>mkdir -pv $LFS/{proc,sys}</userinput></screen>
<para>Now mount the file systems:</para>
<screen><userinput>mount -vt proc proc $LFS/proc
mount -vt sysfs sysfs $LFS/sys</userinput></screen>
<para>Remember that if for any reason you stop working on the LFS
system and start again later, it is important to check that these file
systems are mounted again before entering the chroot
environment.</para>
<para>Additional file systems will soon be mounted from within the
chroot environment. To keep the host up to date, perform a <quote>fake
mount</quote> for each of these now:</para>
<screen><userinput>mount -vft tmpfs tmpfs $LFS/dev
mount -vft tmpfs tmpfs $LFS/dev/shm
mount -vft devpts -o gid=4,mode=620 devpts $LFS/dev/pts</userinput></screen>
