26# For modifying the behavior of rmtmpfiles, do not edit this script.
27# Instead use svccfg(8) to modify the SMF repository.  To achieve
28# traditional System V treatment of /var/tmp, invoke the following
29# commands.:
30#
31# # svccfg
32# svc:> select system/rmtmpfiles
33# svc:/system/rmtmpfiles> setprop options/clean_vartmp="true"
34# svc:/system/rmtmpfiles> select default
35# svc:/system/rmtmpfiles:default> refresh
36# svc:/system/rmtmpfiles:default> exit

39# Traditional SunOS 4.x behavior has been to not remove directories in
40# the /tmp directory; only simple files were removed. This lead to an
41# inconsistency when the tmpfs file system was used (which isn't persistent
42# across boots. The following adopts the traditional System V behavior
43# of removing everything in /tmp, unless /tmp or any of its subdirectories
44# are mount points for another filesystem.
