Hi

Uff i find error. Under the "Udev events" i get:

unable to handle paging request<7>unionfs: do delay copyup "i2c-algo-bit.ko"

EDIT2:
Everything is ok on kernel < 2.6.22 or kerne 2.6.22 with aufs wink

Yes, I've noticed the problem with unionfs on 2.6.22. I think we'll have to use aufs for now.

Re: live Arch CD construction kit (larch)

Ok gradgrind, I understand.
Thank you for your answer and for your work on larch smile

I am going to give it a try to make a liveUSB ....

Re: live Arch CD construction kit (larch)

Does the repository contain x86_64 packages also?

Or they are only for i686?

You see my main PC is an amd64 and I would like to give larch a try.

I know I can build a x86 chrooted environment on a amd64 machine using linux32, but I do not know if larch supports this.

Re: live Arch CD construction kit (larch)

In principle there is no reason I know of why larch could not be used on a 64-bit system with 64-bit packages. All the larch scripts are just bash scripts, so it should be architecture independent.

Unfortunately there is one catch. I am recommending using aufs at the moment instead of unionfs, because unionfs does not work with kernel 2.6.22. aufs does not yet support 64-bit processors.

Practically that means, I guess, that only 32-bit live systems can be built at the moment. As to whether that could be done from your 64-bit environment, I'm afraid I have no idea - I don't have a 64-bit processor and so I can't try anything out. If you haven't got space for or don't want a 32-bit system on your disk, you could try from a (32-bit) live CD - just make sure that the larch build gets done somewhere where there's enough space.

Re: live Arch CD construction kit (larch)

Thank you.

Another option I have is to build the larch system on a remote x86 machine via ssh (it is running Arch i686). It has a lot of disk space.

I only hope the process is not too CPU intensive because that machine is not very powerful (a Celeron Tualatin @ 1.3GHz with 1GB of RAM).

Just built a slightly tweaked default profile CD on a 800Mhz thinkpad with 256MB Ram. So you should be good to go. smile

Re: live Arch CD construction kit (larch)

I gave it a try.

I used the mini-2 profile, customized it further for my need, and produced a backup / restore / rescue CD.

One question though.

What is the default root password?

Because I was trying to do a root ssh from the LAN.

There is no root password, that is why ssh won't work out of the box. There is a chapter on ssh access in the docs.

No, sorry, it's one of those freebies. But you don't really need it. The repos are here:
ftp://archie.dotsrc.org/projects/archie/larch/dev3A
http://www.faunos.com/larch/repo

Just download larch-setup.sh to an empty directory, run it, and you'll have the larch scripts set up and ready to go.
The documentation is in larch/share/larch/docs/html.

Actually I needed the documentation since I had not saved it from the site.

But now I did find it indeed on my disk.

Re: live Arch CD construction kit (larch)

About enabling root ssh login, it seems I have three options:

a. Use an RSA key
b. Permanently set the root password to something other than blank
c. Set "PermitEmptyPasswords" to "yes" in /etc/ssh/sshd.conf

Which one do you suggest?

I consider a to be a lot of fuss and too complicated.

I do not know how to implement b, although if it's possible and not too complicated I would go for it.

On the other hand, c is easy to implement. Security issues are not a problem since this is a small live-CD I only need for maintenance-rescue use in my SOHO LAN.

Re: live Arch CD construction kit (larch)

I'd say in your situation (c) might indeed be the simplest. I don't think (a) is particularly complicated (generate the file and copy it into the overlay), (b) can be done either by copying a suitable /etc/shadow (possibly a little tricky) into the overlay or by using session-save after running passwd on the running live system.

Re: live Arch CD construction kit (larch)

wantilles, you can do a  echo "root:your_password" | chpasswd  in /etc/rc.local (and copy  overlay)

Re: live Arch CD construction kit (larch)

The larch website is now on berlios. I'll gradually move the code development (svn) there, too.
