Update of /a/cvsroot/src/distrib/utils/sysinst
In directory netbsd1:/var/slash-tmp/cvs-serv10100

Modified Files:
        defs.h disks.c label.c menus.mi.eng msg.mi.eng net.c target.c 
        upgrade.c util.c 
Log Message:
* Add main menu option to reinstall sets or install additional sets.
  (like upgrade but without trying to save etc.

* Add option to setls0urce menu to look in an already-mounted (local)
  directory.  Change `local fs' option to say umounted local fs.

* Change extract_file() to check that a tarball actually exists
  and give an explicit non-curses warning if it doesn't. (see above.)

* GNU tar returns a successful status if its gunzip child dies.
  Add short sleep() after tar commands in case of undetected errors.

* Change set-source selection code (except FTP, floppy) to check
  that the mandatory set files (base.tgz, etc.tgz) exist
  in the selected directory.  If they don't, warn the user and 
  prompt the user to  change the selected directory.
  Give the user the option to explicitly continue even if
  base.tgz or etc.tgz not found, just in case.

* Change extract_file() to keep count of set unpacks that succeeded
  or failed. (Unreliable, given the broken return status of gnu tar.)
  Warn the user if there are errors and abort the installation/upgrade
  if we find any.  Does at least catch Ctrl-C interrupts of unpacking.

* Make unwind_mounts() signal-safe.

* Sense of target_verify_* is broken. Replace with predicates that
  return 1 iff the file or directory exists.

* Fix upgrade tests for existing etc.old (see above) before saving
  target /etc as /etc.old.

* Other detail fixes.
