| 7 | <para>Various file systems exported by the kernel don't exist at all on your
|
---|
| 8 | hard drive, but are used to communicate things to and from the kernel itself.</para>
|
---|
| 9 |
|
---|
| 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>
|
---|
| 18 |
|
---|
[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
|
