Hi Folks,

  I recently updated one of my hosts with STABLE via "make installworld" and
mergemaster.  After the update, I found something strange.
  /usr/src and /usr/obj gets empty after peropdic daily is executed via
/etc/crontab.

# ls -l /usr /raid1
/raid1:

  As you see above, /usr/src and /usr/obj are symlinked to /raid1/usr.src
and /usr/obj, respectively so both /usr and /raid1 are shown.
  Pay attention to the date of usr.obj and usr.src.  These two directories
are ALWAYS emptied then set date to " Aug 14 01:20" (JST).  I looked through
/usr/periodic/daily/* and found nothing.  Does anyone here know what the
heck is going on?

  FYI the server here is my scratch server so I have lost nothing important.
But I am too scare to test the update on other servers.
