17. Now that you have successfully created a working mini |
|
|
|
distribution from Example.yard, re-create it with a different |
|
|
|
filesystem type: ext2, minix, reiserfs, romfs or cramfs. |
|
|
|
|
|
|
|
<p> |
|
|
|
|
|
|
|
18. Open up the Filesystem Box (Edit->'File System") and click on |
|
|
|
the UML Exclusively check button, and enter a filesystem command. For this |
|
|
|
example <code>genromfs</code> will be used to create a read-only romfs. |
|
|
|
Normal users will want to keep the Preserve Permissions check |
|
|
|
button off. Press the submit button when finished. |
|
|
|
|

<p> |

|
19. Adjust the Filesystem Size in the ARS larger than 8192k, you |
|
|
|
could also make it smaller, but the point of this exercise is to introduce |
|
|
|
users to how the 8192k barrier of genext2fs can be exceeded. |
|
|
|
|
|
|
|
<p> |
|
|
|
|
|
|
|
20. Normal users should make sure the staging behavior is user |
|
|
|
defined, and press on the Create check button on the Yard Box. |
|
|
|
Press Continue and observe what happens. Root users should have |
|
|
|
made the original filesystem with genext2fs, if not, they need to go |
|
|
|
through steps 12-16 again after entering <code>genext2fs -z -r0</code> in the |
|
|
|
Filesystem Box. |
|
|
|
|
|
|
|
<P> |
|
|
|
|
|
|
|
21. Do step 16. You may notice complaints on boot-up |
|
|
|
about ioctl.save, to remove these complaints you could create a replacement |
|
|
|
ioctl.save, edit the template, re-create the filesystem, and test again. |
|
|
|
|
|
|
|
<p> |
|
|
|
|
|
|
|
22. So what about devices for normal users? |
|
|
|
Genext2fs creates devices for normal users, however, when UML Exclusively |
|
|
|
is used a normal user doesn't have the capability to copy over devices |
|
|
|
from the host system. Instead, devfs should be used. |
|
|
|
If more devices are required, devfsd can be used to set them up after the |
|
|
|
root filesystem is booted. Did you get things to work? |
|
|
|
Congratulations, you have created a root filesystem larger than 8192k without |
|
|
|
needing to be root! |
