What exactly is the issue? As always: pls describe the error meticulously, add error messages and misbehaviour.


What I can say from looking at your script is that shell variables are not expanded within single quotes, so neither $user_name nor $passwd values will be passed to the .*profile files. If that is by intention, make sure the vaiables are defined in those scripts.

ucf.conf

UCF.CONF(5)						      Debian GNU/Linux manual						       UCF.CONF(5)

NAME

       ucf.conf - site-wide configuration file for ucf

SYNOPSIS

       /etc/ucf.conf

DESCRIPTION

       The file /etc/ucf.conf is actually a Bourne Shell snippet included during the package build process, and hence you may put any shell direc-
       tive in that file (just make very sure you know what you are doing).

       All the variables have reasonable default values, and some may be overridden on a per run or a per individual basis  by	using  environment
       variables, and all configurable variables can be overridden by options to the scripts themselves.

       The value of a variable can be set so:

       a) Defaults exist in the rules file. These are the values used if no customization is done.

       b) Some variables can be set in the config file /etc/ucf.conf.  These values override the defaults.

       c) Some variables can also be set by setting a corresponding environment variable.  These values override the config file and the defaults.

       d) Using script command line options. All configurable variables may be set by this method, and will override the other methods above.

Configuration File options
       At the moment, the user modifiable variables supported are:

       DEBUG		 Debugging  information: The default value is 0 (no debugging information is printed). To enable debugging output, set the
			 value to 1.

       VERBOSE		 Verbosity: The default value is 0 (quiet). To change the default behavior, set the value to 1.

       conf_force_conffold
			 Force the installed file to be retained. The default is to have this variable unset, which makes the script ask  in  case
			 of doubt.  This can be overridden by the environment variable UCF_FORCE_CONFFOLD

       conf_force_conffnew
			 Force the installed file to be overridden. The default is to have this variable unset, which makes the script ask in case
			 of doubt.  This can be overridden by the environment variable UCF_FORCE_CONFFNEW

       conf_source_dir	 This is the directory where the historical md5sums for a file are looked for.	Specifically, the historical  md5sums  are
			 looked for in either the file ${filename}.md5sum, or the subdirectory ${filename}.md5sum.d/

       conf_old_mdsum_file
			 Force	the  historical md5sums to be read from this file, rather than defaulting to living in the source directory.  Set-
			 ting this option overrides settings in the environment variable UCF_OLD_MDSUM_FILE

Files
       System-wide defaults are placed in /etc/ucf.conf,

BUGS

       There are no bugs.  Any resemblance thereof is delirium. Really.
