pbuilder problems



Hi :)

I'm trying to setup pbuilder on one of my virtual Hurd
systems. Problem is that debootstrap eventually dies:

 /var/cache/apt/archives/readline-common_6.2+dfsg-0.1_all.deb
 /var/cache/apt/archives/xz-utils_5.1.1alpha+20120614-2_hurd-i386.deb
(Reading database ... 6919 files and directories currently installed.)
Unpacking apt (from .../apt_0.9.8.2_hurd-i386.deb) ...
dpkg: error processing /var/cache/apt/archives/apt_0.9.8.2_hurd-i386.deb (--unpack):
 unable to install new version of `./usr/lib/apt': Resource temporarily unavailable
dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)

dpkg-deb: error: subprocess paste was killed by signal (Broken pipe)
[.. more errors like this..]

I suspect that something funny goes on in the rootfs translator (it's
an one filesystem setup, maybe I should create another filesystem to
protect the rootfs), b/c I end up with an mostly empty /dev:

% ls /dev
cons fd null vcs

Not sure if anything else got corrupted, I noticed the /dev issue b/c
it renders the system unbootable. Fortunately reinstalling the hurd
package fixes this. I've been able to reproduce this whole issue once.

Then again, it could be some mach issue b/c the network connection
also dies shortly after the this and the system is in a bad
shape. E. g. ls /proc shows /proc/meminfo, but opening that file fails
with no such file.

The Debian/Hurd system is an up-to-date debian/sid
debian-ports/unreleased system. It has 512 megs of RAM and 300 megs
swap, all of which is unused. vmstat shows 200 megs of free RAM
*now*. The system is still running and accessible via console. Any
hints how to debug this further would be appreciated.

Fwiw the host is Debian/Linux wheezy, virtualization is
libvirt/kvm. kvm invocation:

/usr/bin/kvm -S -M pc-1.1 -cpu Opteron_G3,+ibs,+osvw,+3dnowprefetch,+cr8legacy,+extapic,+cmp_legacy,+3dnow,+3dnowext,+pdpe1gb,+fxsr_opt,+mmxext,+ht,+vme -enable-kvm -m 512 -smp 1,sockets=1,cores=1,threads=1 -name hurdbox -uuid 207e086a-7ab4-e39d-6655-effed9ec2280 -no-user-config -nodefaults -chardev socket,id=charmonitor,path=/var/lib/libvirt/qemu/hurdbox.monitor,server,nowait -mon chardev=charmonitor,id=monitor,mode=control -rtc base=utc -no-shutdown -device piix3-usb-uhci,id=usb,bus=pci.0,addr=0x1.0x2 -drive file=/media/sdb2/libvirt-pool/hurdbox.img,if=none,id=drive-ide0-0-0,format=qcow2,cache=writeback -device ide-hd,bus=ide.0,unit=0,drive=drive-ide0-0-0,id=ide0-0-0,bootindex=2 -drive if=none,id=drive-ide0-1-0,readonly=on,format=raw -device ide-cd,bus=ide.1,unit=0,drive=drive-ide0-1-0,id=ide0-1-0,bootindex=1 -netdev tap,fd=20,id=hostnet0 -device rtl8139,netdev=hostnet0,id=net0,mac=52:54:00:6b:6d:f7,bus=pci.0,addr=0x3 -chardev pty,id=charserial0 -device isa-serial,chardev=charserial0,id=serial0 -vnc 127.0.0.1:0 -k en-us -vga cirrus -device intel-hda,id=sound0,bus=pci.0,addr=0x4 -device hda-duplex,id=sound0-codec0,bus=sound0.0,cad=0 -device virtio-balloon-pci,id=balloon0,bus=pci.0,addr=0x5

Am I missing something?
