Hi, |
| 2 |
|
| 3 |
Before posting a question in a mailing list, I'd rather have a look in |
| 4 |
the archive. Is there an archive of this gentoo catalyst mailing list ? |
| 5 |
|
| 6 |
I am trying to build a gentoo liveCD. I used gentoo catalyst reference |
| 7 |
manual, spec file examples distributed with this reference manual and |
| 8 |
the "howto build a liveCD" from the Gentoo wiki. Each step is a |
| 9 |
challenge. If I have success, I'll try to publish complementary notes, |
| 10 |
especially, for the traps I encoutered (kernel panic due to ramfs size, |
| 11 |
CDROM not known, squashfs patch...). Publication of a minimal liveCD |
| 12 |
subset of the kernel config parameter would probably be a great help |
| 13 |
for me. |
| 14 |
|
| 15 |
I have two questions: |
| 16 |
A) The goal of that livecd is a zero installation virtual model for |
| 17 |
network lab. It's based on VNUML (Virtual Network User Mode Linux |
| 18 |
http://www.dit.upm.es/vnuml/) a spanish project based on usermode |
| 19 |
linux.(UML). |
| 20 |
As the liveCD will be used to launch UML (usermode linux) virtual |
| 21 |
machines , I need a SKAS (Single Kernel Address Space) patched kernel on |
| 22 |
the liveCD. The Blaisorblade's SKAS patch |
| 23 |
(http://www.user-mode-linux.org/~blaisorblade/patchlist.html) is not |
| 24 |
avalaible in the official gentoo kernel package database, what is the |
| 25 |
best way to intergrate my specific skas kernel on the liveCD? I have not |
| 26 |
found how to automatically integrate specific kernel patch on the |
| 27 |
development-sources during the catalyst stage2 or the genkernel step. |
| 28 |
What I plan to do is to uncompress the iso file, change the kernel in |
| 29 |
the isolinux dir and compress again the iso file. Is there a more |
| 30 |
elegant way? Is it possible to force catalyst to use a local kernel |
| 31 |
source dir instead of one of the on-line sys-kernel source package ? |
| 32 |
|
| 33 |
B) As this liveCD will be used in a pedagogical computer lab, I would |
| 34 |
like it to boot as a generic user, instead of the root. I don't want the |
| 35 |
student having superuser rights on the real host (student will have |
| 36 |
superuser rights in the usermode virtual machine). What is the best way |
| 37 |
to do a "user livecd" with catalyst ? |
| 38 |
|
| 39 |
And a note : I test my liveCD iso file using QEMU virtual machine |
| 40 |
instead of burning it. With 2.6.x kernel QEMU need "clock=pit" param |
| 41 |
when kernel is launched. In the python sources of catalyst I found a |
| 42 |
"/boot/kernel/xxx/kernelopts" parameter which can append kernel |
| 43 |
parameters in the isolinux.cfg file. I 'll probably add a gentoo-qemu |
| 44 |
kernelboot to have a "qemu" entry in the isolinux. |
| 45 |
This "/boot/kernel/xxx/kernelopts" is not refered in the catalyst |
| 46 |
reference manual. I think in a future version of the reference manual, |
| 47 |
it would be a good idea to mention it. |
