# initdefs - 06/14/93
#
# initdefs - 05/03/2010 - - Fixed the problem with delete() function in
# initdefs which prevented it from deleting multiple files if
# it failed with one of them (Debian bug #544701)
#
# initdefs - 01/10/2005 - cslater - Modified ignore function so that
# filtering can also be done on msgid and level
# initdefs - 08/01/2004 - jfs - Allow removal from LOGDIR so that tiger -e
# works as expected
# initdefs - 10/15/2003 - jfs - Quoted $__File in deleted() in order
# for the check_rootkit check to work properly.
# (Debian bug #215882)
# initdefs - 10/10/2003 - jfs - Improved check so that it will not
# remove files created by a different user and
# warn if files to be deleted do not exist
# (currently disabled since some checks remove things
# twice)
# initdefs - 09/20/2003 - jfs - Fixed have_allvars since it was not working
# initdefs - 09/19/2003 - jfs - Different error messages in have_allvars.
# Applied patch from Ryan Bradetich to fix UID -> UUID
# initdefs - 08/13/2003 - jfs - Run_script now returns error number
# initdefs - 08/09/2003 - jfs - Delete now checks if RM exists
# initdefs - 08/08/2003 - jfs - Added safe_temp and run_script functions
#
#-----------------------------------------------------------------------------

# Routines for verifying environment

# haveallcmds - verify command variables

# haveallvars - verify variables

# Note:
# In some cases haveallcmds might fail if the program is not installed
# (such as when looking for SNEFRU) it might be necessary to have config
