| 10 | <para>Begin by creating directories onto which the file systems will be mounted:</para>
|

| 11 |
|

| 12 | <screen><userinput>mkdir -p $LFS/{proc,sys}</userinput></screen>
|

| 13 |

| 14 | <para>Now mount the file systems:</para>
|

| 15 |
|

| 16 | <screen><userinput>mount -t proc proc $LFS/proc
|
|---|
| 17 | mount -t sysfs sysfs $LFS/sys</userinput></screen>

| [10fb6a5] | 19 | <para>Remember that if for any reason you stop working on your LFS, and start
|
|---|
| [9dfc02f] | 20 | again later, it's important to check that these file systems are mounted again
|
|---|
| 21 | before entering the chroot environment, otherwise problems could occur.</para>
|

| 22 |
|

| 23 | <para>Shortly, we'll be mounting a few more file systems from within the chroot
|
|---|
| 24 | environment. To keep the host up-to-date, we'll do a <quote>fake mount</quote>
|
|---|
| 25 | for each of these now:</para>
|

| 26 |
|

| 27 | <screen><userinput>mount -f -t ramfs ramfs $LFS/dev
|
|---|
| 28 | mount -f -t tmpfs tmpfs $LFS/dev/shm
