Package: debian-installer
Severity: normal

Dear Maintainer,

I have observed some failures when running debian-installer in a
paravirtualized Xen environment, but I do not believe that this issue
is necessarily limited to paravirtualized Xen.

When running the installer with a preseed file, installation fails
at random points during the process.  For instance, I have seen it
fail as soon as the "choose language" step.  Or it may fail when
downloading installer components.   In some instances, the file
/var/lib/dpkg/info/lilo-installer.isinstallable goes missing, and the line
"d-i lilo-installer/skip boolean true"
from my preseed file is ignored.

When manually running the installer, the program has been known to
fail at the first step, "choose language".

I spent some time tracking down the problem, and I believe it is
caused by race conditions due to running multiple copies of the installer
in parallel.  My Xen domU is booted with the kernel command line
"console=hvc0", and /proc/consoles has two entries: hvc0 and tty0.

I have not seen the issues described above on a system that only has one
entry in /proc/consoles.  For instance, a Xen domU using HVM
virtualization and booted with the kernel command line "console=ttyS0"
only has a single entry in /proc/consoles.

Closes: 930970 932416 940028
 rootskel (1.132) unstable; urgency=medium
   [ Helmut Grohne ]
   * Fix FTCBFS: Make gcc substitutable. (Closes: #930970)
   [ Samuel Thibault ]
   * src/usr/lib/finish-install.d/06rootskel: Rename to 07rootskel to have
     users set up. Enable high-contrast theme when installation was made with the
     dark theme. Enable compiz ezoom features for accessibility.
   [ Dimitri John Ledkov ]
   * Specify fs_spec field in fstab-linux mount points. Some tools parse
     /proc/mounts and try to match on the spec field to find where sysfs is
     mounted (ie. dasdfmt on s390x). This makes d-i environment look more
     similar to the installed systems.
   [ Steve McIntyre ]
   * Tweak how multiple consoles are used. If we detect that we're
     trying to run using preseeding, do *not* run on multiple consoles
     in parallel as that causes race conditions and weird
     behaviour. Instead, just run on the "preferred" console.
     Closes: #940028, #932416
