Root script for emergency disk clearing

A straightforward script could be used to clear space in cases where the disk hits the overflow level. This script tidies the whole system, not just the affected disk.

#!/local/gnu/bin/cfengine -f
#
# Emergency tidyup!
#
# (Users read their cfengine.rm files to see what got deleted!)
#

control:

site = ( mysite )

mountpattern = ( $(site)/$(host) )
homepattern   = ( u? )

actionsequence =
   (
   tidy
   )

tidy:

      home            pattern=core   R=inf   age=0
      home            pattern=*~     R=inf   age=0
      home            pattern=*.dvi  R=inf   age=1
      home            pattern=*.o    R=inf   age=0
      /tmp            pattern=*      R=inf   age=0  # could be risky
      /usr/tmp        pattern=*      R=inf   age=0  #      "
