Title:
  libc6-xen:i386 installation can cause panics on boot

Status in “eglibc” package in Ubuntu:
  Confirmed

Bug description:
  The eglibc package produces a special libc6 package for i386 Xen
  installations. This gets depended on by i386 Xen installs and causes
  (via some ld.config rule) binaries to dynamically link against those
  libraries. So while running inside a Xen guest (which dom0 is) the
  following is true:

  #> ldd /bin/sh
          linux-gate.so.1 =>  (0xb7734000)
          libc.so.6 => /lib/i386-linux-gnu/tls/i686/nosegneg/libc.so.6 (0xb757900)
          /lib/ld-linux.so.2 (0xb7735000)

  This creates a problem when update-initramfs is called inside dom0
  because the automatic library resolver will only pick up the special
  ones. When the host then gets rebooted into non-xen mode, this causes
  a panic on boot because the standard libraries are not included in the
  initramfs.
