Update of /a/cvsroot/src/distrib/utils/sysinst
In directory netbsd1:/var/slash-tmp/cvs-serv15647

Modified Files:
        defs.h net.c target.c upgrade.c 
Log Message:
Add more target_wrapper functions, to do
  * renames of files from one pathname within the  target to another
    (e.g., mv_within_target_or_die("/etc", "/etc.old");
  *  check to see  if a partition name like "sd0a" is the current root
  *  Duplicate a file from the current root into the target root
     (for copying /netbsd from RAMdisk into the  target). 
     A no-op if the root is the install target).
Start using these where appropriate.

Change net.c to avoid losing any information when updating network
config files: where possible, do appends to files that might have more
info than we got from the user (e.g., /etc/hosts.)

Where possible, add comment saying file was created/modified by sysinst.
