Subject: debootstrap failes without error, on the first run, if resolv.conf is a broken symlink

Date: Mon, 02 Oct 2006 14:00:24 +0200

[Message part 1 (text/plain, inline)]

Package:debootstrap
Version: 0.3.3
Severity: minor

This error might be more a resolvconf bug, but i'd expect a better error
message from debootstrap too.

I am using the debian etch beta3 cd installer, and a custom udeb
ltsp-client-builder.
The purpose of this udeb is to create a ltsp chroot in
the /target/opt/ltsp/i386 This udeb runs debootstrap after pkgsel, just
before finish-install. This debootstrap run exits with no error message.
If one examine the debootstrap-target/debootstrap/debootstrap.log file
you see a error message saying
"cat: resolv.conf no such file or directoy"

if you try this in the shell with 
cat /etc/resolv.conf you get the same error, becouse resolv.conf is a
broken link to /etc/resolvconf/run/resolv.conf


How to reproduce:
1. run the beta3 installer until the next step is "finish install".  
2. swap to tty2 
3. chroot /target 
4. run debootstrap etch /opt/ltsp/i386 file:///cdrom

You can workaround the problem by either run debootstrap twice in
succession. 
Or by touch /etc/resolvconf/run/resolv.conf before running debootstrap.

Subject: debootstrap breaks on broken symlink /etc/resolv.conf

Date: Sat, 07 Oct 2006 23:12:22 +0200

Tags: patch

resolv.conf in debootstrap chroot is copied from the resolv.conf on the 
host where debootstrap is executed. the file 
/usr/lib/debootstrap/functions, contains the line 

conditional_cp /etc/resolv.conf "$TARGET"

conditional_cp () {
 if [ ! -e "$2/$1" ]; then
   if [ -L "$1" ]; then
     cat "$1" >"$2/$1"
   elif [ -e "$1" ]; then
     cp -a "$1" "$2/$1"
   fi
 fi
}

but when /etc/resolv.conf is a broken symlink. As it is in the debian 
installer until the system is rebooted and resolvconf populates it.
the command cat "$1" >"$2/$1"  gives a "no such file or directory" and 
debootstrap exits abnormally.

a modification to forinstance

conditional_cp () {
 if [ ! -e "$2/$1" ]; then
   if [ -L "$1" -a -e "$1"]; then
     cat "$1" >"$2/$1"
   elif [ -e "$1" ]; then
     cp -a "$1" "$2/$1"
   fi
 fi
}


Would check that the source also exsisted before trying to cat it.

More knowledgeable people in debian-devel suggested

conditional_cp () {
 if [ ! -e "$2/$1" ]; then
   if [ -L "$1" ] && [ -e "$1" ]; then
     cat "$1" >"$2/$1"
   elif [ -e "$1" ]; then
     cp -a "$1" "$2/$1"
   fi
 fi
}


as a more  portable and less syntactically ambiguous method

Package: debootstrap
Version: 0.3.3
Followup-For: Bug #390647

attached patch based on the information provided in this bug report,
though it handles broken symlinks by skipping those files, which is
maybe not ideal.

live well,

thanks

Hi,

since 3 years we work around this bug (*), which has a (IMO) straightforward 
patch, but yet never seen a reply from the maintainers. Any chance to see 
this fixed for squeeze?


cheers,
	Holger

(*) in 
$svn/debian-edu/trunk/src/edu-ltsp-client-builder/debian/ltsp-client-builder.postinst 
which I think is also used in the ltsp proper packages...

   [ Guillem Jover ]

 .
   [ Frans Pop ]
   * Use tab indentation in scripts/debian/sid to reduce its size (relevant
     for Debian Installer).
   * Add apt to base packages for the buildd variant as it is no longer marked
     Build-Essential.
 .
   [ Otavio Salvador ]
   * Apply patch from Andres Salomon <dilinger@collabora.co.uk> to honor
     --components when using mirror_style 'main' (closes: #561283).
   * Apply patch from Andres Salomon <dilinger@collabora.co.uk> to fix

 .
   [ Joey Hess ]
   * Allow the suite to be stable, testing, or unstable when debootstrapping
     Debian. Closes: #288109
   * Make scripts directory in source tree look like installed directory,
     and add a section to README explaining an easy way to run
     debootstrap w/o installing it. Closes: #345762
   * Convert rules file to use dh with overrides.
   * Remove binary-basedebs target from debian/rules.
     This target has been broken in multiple ways since 2007. While I
     accidentially partially fixed it with the above changes, this is evidence
     it's dead code that can be safely removed.
