exec 1>>/tmp/tmp.log; exec 2>>/tmp/tmp.log
Two file handles for the same file? I guess this can loose some previous writes when switching to the other handle.
Correct is
Code:
exec 1>>/tmp/tmp.log 2>&1

DH-EXEC-INSTALL(1)						      dh-exec							DH-EXEC-INSTALL(1)

NAME
dh-exec-install - Install (and possibly rename) files. SYNOPSIS
#! /usr/bin/dh-exec debian/default.conf => /etc/my-package/start.conf usr/bin/* DESCRIPTION
Being a sub-command of dh-exec(1), this program must not be ran directly, but through dh-exec, which automatically runs all available sub-commands if run bare; or explicitly with dh-exec --with=install. It is meant to be used for dh_install(1) files, and those alone. If it finds that its input is not such a file, it will do nothing, but echo back the contents. The purpose of the program is to extend dh_install(1)'s functionality, by allowing to specify a destination filename. This can be accomplished by a special syntax: the " => " mark between a source and a destination means that the source file should be installed with the specified destination name. For obvious reasons, the source must not be a wildcard, and the destination in this case must be a file, and not a directory. All other non-comment lines are left alone. RESTRICTIONS
Due to the way executable scripts are called from debhelper(1), there is no way to know what options were used for the original dh_install(1). This means, that the --sourcedir option of dh_install(1) will not work correctly when dh-exec-install is in use. IMPLEMENTATION
Internally, the renaming happens by creating a temporary directory under debian/tmp/, and copying (or moving, if the source was under debian/tmp/ to begin with) the file there, with the new name. This is done this way to allow dh_install(1) to do the real copying, and allow its options to continue working, even when renaming is involved. The temporary directory is put under debian/tmp so that it will be cleaned by dh_prep(1) when the clean target gets to run. Thus, no extra code is needed anywhere to clean up the renamed files. ENVIRONMENT
DH_EXEC_SCRIPTDIR Indicates which directory the command-specific scripts should be sought for. If not specified, scripts will be searched for in /usr/share/dh-exec/. FILES
