10 | <para>Various file systems exported by the kernel are used to communicate to and
|
---|
11 | from the kernel itself. These file systems are virtual in that no disk space is
|
---|
12 | used for them. The content of the file systems resides in memory.</para>
|
---|
13 |
|
---|
14 | <para>Begin by creating directories onto which the file systems will be mounted:</para>
|
---|
15 |
|
---|
16 | <screen><userinput>mkdir -pv $LFS/{proc,sys}</userinput></screen>
|
---|
17 |
|
---|
18 | <para>Now mount the file systems:</para>
|
---|
19 |
|
---|
20 | <screen><userinput>mount -vt proc proc $LFS/proc
|
---|
21 | mount -vt sysfs sysfs $LFS/sys</userinput></screen>
|
---|
22 |
|
---|
23 | <para>Remember that if for any reason you stop working on the LFS
|
---|
24 | system and start again later, it is important to check that these file
|
---|
25 | systems are mounted again before entering the chroot
|
---|
26 | environment.</para>
|
---|
27 |
|
---|
28 | <para>Additional file systems will soon be mounted from within the
|
---|
29 | chroot environment. To keep the host up to date, perform a <quote>fake
|
---|
30 | mount</quote> for each of these now:</para>
|
---|
31 |
|
---|
32 | <screen><userinput>mount -vft tmpfs tmpfs $LFS/dev
|
---|
33 | mount -vft tmpfs tmpfs $LFS/dev/shm
