Subject: Re: [Minix-devel-l] Symbolic link
Using an alias for cd to set the prompt to display the current path
breaks the cd command.  I use in .ashrc:
PS3=$PS1
hostname=$(expr `cat /etc/hostname.file` : '\([^.]*\)')
cd() {          ## shows current directory as prompt
   command cd "$@"
   PS1="$PS3$USER@$hostname:`pwd` > "
}
If you change the macro in shell.h to:
#define SYMLINKS  0
the correct behaviour is restored.  Could you verify?
I think that the ash package needs the patch.
