d-i preseed/late_command to append a file content in the user's .bashrc

[Federico Bruni <fede@inventati.org>]

Hi all

I'm trying to append my custom bash configuration to ~/.bashrc through 
preseed.cfg. I used this line at the end of my preseed.cfg:

d-i preseed/late_command string cat /etc/skel/.mystuff-bashrc >> 
~/.bashrc

But it fails with exite code 1, without any further information. What's 
wrong in above line?
I assumed that at the end of the installation the user home is already 
created and populated with files. Wrong assumption?

I used to use config/includes.chroot/etc/skel/.bashrc to define my own 
.bashrc, but I think that I'd better put my changes in another file and 
then append them to the default .bashrc. This approach has two 
advantages:

1. No need to maintain my .bashrc when upgrading Debian.
2. If user messes up the bash files in the home, he can restore them 
easily:

  cp /etc/skel/.bashrc ~/.bashrc
  cat /etc/skel/.mystuff-bashrc >> ~/.bashrc

Thanks in advance
Federico
