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

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

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

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

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.

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.

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.

wantilles · 2007-09-30 18:45:04

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.

The site has been down since yesterday.

Any idea as to when it is going to be back up?

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.

wantilles · 2007-10-18 11:55:23

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.

gradgrind · 2007-10-18 17:36:15

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.

Fatsobob · 2007-12-02 16:12:14

What are you gonna do no grad since the hosting site is gone.

callista · 2007-12-03 13:19:50

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

callista · 2007-12-03 13:30:52

wantilles, you can do a echo "root:your_password" | chpasswd in /etc/rc.local (and copy it into overlay).
Its not secure, but it works

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