Re: [gentoo-user] On what to base a custom live CD?
I'd suggest SystemRescueCD. It's upgraded quite often (currently using kernel 2.6.35-x) has a ready to go X11 environment and most useful, it's an up-to-date Gentoo system, so one immediately knows where to look if there are any problems. And it has a well documented (easy) procedure for extending it. Helmut. On 11/24/10 23:02:10, Grant Edwards wrote: I need to build a liveCD that boots on as wide a variety of hardware as is practical. It needs to load one custom kernel module and then run one console-mode application. Instead of building something from scratch, I was hoping I might be able to modify an existing liveCD. There's no need for support for networking, graphics, or even access to optical or hard drives. The current version of this CD is built sort of from scrach using a labor-intensive and error-prone process. However, it does produce something that's small (less that 10MB), and boots fast (around 10 seconds). But, updating the existing CD with a newer kernel (to gain support for newer hardware) is difficult. I thought about using a customized systemrescuecd, but that takes ages to boot (almost 5 minutes).

It it actually booting all that time, or is it waiting for user input? I doesn't take anything like that long to boot on my netbook, but I have modified the USB install to set a keymap choice and a couple of other options. AFAICT, it's booting that whole time. I picked the initial isolinux menu entry that selects the US keymap, so there is no user input until it gets to the bash prompt. That time is booting on a qemu VM (but so is the ~10 seconds for the other CD I'm comparing to). I've since done a little testing with a Thinkpad T510, and the difference between the two CDs isn't nearly as much (maybe 5X instead of 30X). Since I don't need much in the way of resources (no networking or hard-drive acess) I've been thinking about ditching the squashfs stuff completely and just putting everything I need in the initrd image. That way I can disable the both the networking and IDE/PATA/SATA/SCSI support in the kernel. That ought to speed up the boot time considerably.

I only have an empty /sys/fs/cgroup with the following config on 2.6.36,
so please share the kernel config as well.
I guess you have to mount your cgroup there, first. The original link
describes, how.
I don't have a /sys/fs/cgroup at all. So I don't think my kernel config
will help you.
My solution isn't that great, anyway. I thought about writing an init
script but I haven't done that yet and don't think I'll do it soon.
Anyway, if you want my solution, here it is, although it's mostly
copy'n'paste from the original link:
1. Create '/usr/local/sbin/cgroup_start' with the following content:
#!/bin/bash
mkdir -p /dev/cgroup/cpu
mount -t cgroup cgroup /dev/cgroup/cpu -o cpu
mkdir -m 0777 /dev/cgroup/cpu/user
/bin/echo '/usr/local/sbin/cgroup_clean' /dev/cgroup/cpu/release_agent
(Execution right for root, only)
## Please note ##
Since I had no /sys/fs/cgroup directory to start with and I didn't want
to fiddle with /proc or /sys, I create a new directory /dev/cgroup to
work with. If you have a better directory, you have to adjust all
following code snippets to work on that directory.
Please also note that I use /bin/echo instead of the shell built-in
echo. There is supposed to be a difference in write error detection
between the both which is important to detect problems when you
configure cgroups.
#
2. Create '/usr/local/sbin/cgroup_clean'
#!/bin/sh
rmdir /dev/cgroup/cpu/$*
(Execution right for root, only)
3.a If you use OpenRC / Baselayout-2, edit /etc/conf.d/local
local_start() {
/usr/local/sbin/cgroup_start
# We should always return 0
return 0
}
3.b If you use Baselayout-1, edit /etc/conf.d/local.start and add
/usr/local/sbin/cgroup_start
## Please note ##
It would be great to know what to do in order to stop using cgroups
again. Then we could create a proper init script for this. Does anyone know?
Can you just unmount it? Do you need to delete its content, first?
#
4. Create a file /etc/bash/local/cgrouprc
if [ $PS1 ] ; then
mkdir -p -m 0700 /dev/cgroup/cpu/user/$$ /dev/null 21
/bin/echo $$ /dev/cgroup/cpu/user/$$/tasks
/bin/echo 1 /dev/cgroup/cpu/user/$$/notify_on_release
fi
5. Edit your own ~/.bashrc file and /root/.bashrc and add the following
line:
source /etc/bash/local/cgrouprc
## Please note ##
The last two steps can be varied as you wish. The creation of a
/etc/bash/local directory is my own policy. It is useful for collecting
common bashrc code that all users can include as they wish.
#
Then call `/etc/init.d/local restart` and type `source ~/.bashrc` in all
your open shells and you are done.
Hope this helps,

I still don't understand why Alan's recommendation works ;-) I'm probably late with my reply, but I'll post it so it will be in the archives for future reference. The man page is actually pretty clear on this issue. Quote: if the pattern starts with a / then it is anchored to a particular spot in the hierarchy of files, otherwise it is matched against the end of the pathname. This is similar to a leading ^ in regular expressions. Thus /foo would match a name of foo at either the root of the transfer (for a global rule) or in the merge-file’s directory (for a per-directory rule). An unqualified foo would match a name of foo anywhere in the tree because the algorithm is applied recursively from the top down; it behaves as if each path component gets a turn at being the end of the filename. Even the unanchored sub/foo would match at any point in the hierarchy where a foo was found within a directory named sub. Root of the transfer is the directory you want to sync. Thus, if you run e.g. rsync /var/log/ /mnt/backups/ --exclude=/portage/ then root of the transfer is /var/log, and therefore the directory /var/log/portage will be excluded. If on the other hand you write --exclude=portage/ then a directory named portage anywhere in the tree under /var/log will be excluded. Without the trailing slash, i.e. just --exclude=portage any file (regular file, directory, link, whatever) named portage anywhere in the tree gets excluded. And finally --exclude=/portage would exclude a file only at the top of the tree that is going to be synchronsed. Hope it helps.

How can i find the motive to this strange (???) problem? I've used --load-average in MAKEOPTS with the same result. When you say freeze, do you mean? A. That the system locks up and you have to restart, or B. That the systems becomes unresponsive, during the compile but returns to normal once the compile is over
[gentoo-user] Console-kit instances...
Hi, is it really necessary, that console-kit runs 65 instances of itsself??? Best regards, mcc
Re: [gentoo-user] Accessing CVS on non-standard port

It's not exposed to the internet but never fear! we have ssh -L and a convenient sshd host that is on the internets. So, locally ssh -Llocalhost::cvs.example.com:22 a...@gateway.example.com and tell cvs that the server is localhost: I do this all the time for lots of other stuff. Doesn't work for CVS because there's no way to tell cvs to tell ssh what port to use. Google gives lots of hits about using the host-specific Host directive in ~/.ssh/config but that won't work for me - it assumes I can see the CVS server directly and doesn't take into account that I have port forwarding in the way. Anyone know a way to get cvs to use any port other than 22? I'm receptive to alternate cvs clients with this support, just not ones that tweak ssh to do it. Use a full-blown tunnel instead of redirection magic. At home: #!/bin/bash modprobe tun ssh -w 0:0 -C -f \ r...@work.example.com \ /root/ssh_tunnel ifconfig tun0 10.0.2.2 netmask 255.255.255.252 # Replace 10.1.1.0/24 with your work subnet. ip route add 10.1.1.0/24 via 10.0.2.1 dev tun0 And on the workstation at work: #!/bin/bash # # /root/ssh_tunnel # # The internal IP of your workstation, on the work network. INTERNAL_IP=10.1.1.x modprobe tun ifconfig tun0 10.0.2.1 netmask 255.255.255.252 echo 1 /proc/sys/net/ipv4/ip_forward # You will probably not want to trash all of your iptables rules. # Adjust as necessary. iptables -F iptables -F -t nat iptables -P FORWARD DROP iptables -A FORWARD -d 10.0.2.0/29 -j ACCEPT iptables -A FORWARD -s 10.0.2.0/29 -j ACCEPT iptables -t nat -A POSTROUTING -s 10.0.2.2 -j SNAT \ --to-source $INTERNAL_IP This worked fine for me for about a year. Eventually, I gave in and set up a real-ass VPN with OpenVPN. If you need to access services remotely often, I would suggest skipping the intermediate step and going straight to OpenVPN.

They're threads... the short of it is... it's already been discussed . It's not hurting anything (much) and upstream takes a better safe than sorry approach (there is a thread to monitor each possible virtual console). It's easy enough to patch if you you think it's a big deal (but it isn't). -a
Re: [gentoo-user] Re: i486
Thanks all, I have a question , when we build the system, always use host client to build the toolchain , then GCC Glibc ...kernel some unity ... from source ,but where the frist system come from ,does it build using the Assembly language or machine language? I mean just give you X86 hardware and power , no OS, no livd cd . I am afraid it is out of this topic.but it always puzzled me :-) On 26 November 2010 03:47, Mick michaelkintz...@gmail.com wrote: On Thursday 25 November 2010 17:40:08 David W Noon wrote: On Thu, 25 Nov 2010 11:10:02 +0100, sam new wrote about Re: [gentoo-user] Re: i486: I have try LFS (linux from scratch) ,and install gentoo use stage3 .Does the stage1 installs like that,Compile the toolchain and build the system? Yes, You have to use the bootstrap compiler to build GCC, even before you build a kernel or glibc. It's long-winded and fairly technically demanding. I recall building a few systems in the early days of gentoo. The funny thing is that other than burning and booting Knoppix a couple of times I had no Linux knowledge or experience. However, the gentoo handbook held my hand step by step and all these years later I'm still here. So, if I could do it, I wouldn't really call it technically demanding. ;-) I guess the OP could use something like this, unless there's a better way documented somewhere else: http://www.gentoo.org/doc/en/faq.xml#stage12 -- Regards, Mick
