# Name : manage_crash_dumps
|

#
|

# Purpose: Prevent crash dumps from filling up the root fs
|
||||
#
|
||||
# The kernel directs new crash dump bundles to
|
||||
# /var/crash/<dated vmcore bundle>. Crash dump
|
||||
# bundles are quite large and, if too many occur,
|
||||
# can fill up its target filesystem.
|
||||
#
|
||||
# This function nicely tars a crash bundle found in /var/crash
|
||||
# to /var/log/crash.
|
||||
#
|
||||
# The first bundle is tar'ed as vmcore_first.tar and preserved.
|
||||
# Subsequent crash bundles are nicely tar'ed as vmcore.tar
|
||||
#
|
||||
# Save the crash dump vmcore summary for all crash dumps.
|
||||
#
|
||||
# Assumptions: logration is used to compress these bundles in the background
