Title:
  failure trying to install from Debian 4.0 (kernel 2.6.18-5)

Status in “debootstrap” package in Ubuntu:
  New

Bug description:
  When trying to run debootstrap (version 1.0.28) to install a new
  current Ubuntu system on a new partition from a running Debian 4.0
  (kernel 2.6.18-5) system I get the following error:

  ) sudo debootstrap --arch i386 lucid /mnt/newsys
  ...
  I: Installing core packages...
  W: Failure trying to run: chroot /mnt/newsys dpkg --force-depends --install /var/cache/apt/archives/base-files_5.0.0ubuntu20_i386.deb /var/cache/apt/archives/base-passwd_3.5.22_i386.deb

  If I manually run that command, I see:

  ) sudo chroot /mnt/newsys dpkg --force-depends --install /var/cache/apt/archives/base-files_5.0.0ubuntu20_i386.deb /var/cache/apt/archives/base-passwd_3.5.22_i386.deb

   /var/cache/apt/archives/base-files_5.0.0ubuntu20_i386.deb
   /var/cache/apt/archives/base-passwd_3.5.22_i386.deb

  If I use strace to track down the source of those errors I see:

  12:52:10.758566 execve("/bin/tar", ["tar", "xf", "-"], [/* 12 vars */]) = 0
  ...
  12:52:10.766846 mkdir(".", 0700)        = -1 EEXIST (File exists)
  12:52:10.766869 stat64(".", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0
  12:52:10.766917 open("./postinst", O_WRONLY|O_CREAT|O_EXCL|O_LARGEFILE, 0700) = 4
  12:52:10.766959 write(4, "#!/bin/sh\nset -e\n\ninstall_local_"..., 5941) = 5941
  12:52:10.767007 close(4)                = 0
  12:52:10.767029 semget(4294967196, 134778280, IPC_CREAT|IPC_NOWAIT|0xbff64000|0100) = -1 ENOSYS (Function not implemented)
  12:52:10.767074 write(2, "tar: ", 5)    = 5
  12:52:10.767172 write(2, "./postinst: Cannot utime", 24) = 24
  12:52:10.767238 write(2, ": Bad file descriptor", 21) = 21
  12:52:10.767302 write(2, "\n", 1)       = 1
  12:52:10.767379 chown32("./postinst", 0, 0) = 0
  12:52:10.767406 chmod("./postinst", 0755) = 0
  ...

  It looks like what tar (or the associated libc) is calling 'utime'
  strace seems to think is 'semget'.  This seems like some sort of
  kernel call / libc incompatibility.  I have tried a few hacks to get
  it to use the tar from the local system (which does seem to work) but
  I can't seem to get it to run the installation without overwriting it
  from the tar package it's installing into the new system.

  Is this tar/syscall problem a known issue? Is there any workaround?
  Or is Debian 4.0 (or the 2.6.18-5 kernel in question) not supported to
  bootstrap a modern system?
