# Generic kdump initramfs manifest
|
|
# 1) Loads all modules
|
|
# 2) Starts all mdraid, lvm partitions
|
|
# 3) Mounts the rootfs
|
|
# 4) Copies /proc/vmcore to /mnt/var/crash/<date>/vmcore
|
|
#
|
|
# Notes on syntax:
|
|
# There are 6 major commands to use when generating manifest files
|
|
# They are:
|
|
# 1) reg
|
|
# reg <source file> <dest path>
|
|
# A regular file copy from the source to the dst directory
|
|
#
|
|
# 2) creg
|
|
# creg <source file> <dest path>
|
|
# like reg, but only copy if the source file exists
|
|
#
|
|
# 3) ren
|
|
# ren <src file> <dst file>
|
|
# rename a file into the initramfs
|
|
#
|
|
# 4) cren
|
|
# cren <src file> <dst file>
|
|
# like creg, but rename the dst file
|
|
#
|
|
# 5) gen
|
|
# gen <binary> <dst file> <options>
|
|
# execute the specified binary, redirecting stdout to <dst>
|
|
#
|
|
# 6) exec
|
|
# exec <binary> <options>
|
|
# execute the specified binary. Option 1 is the
|
|
# base dir where the initramfs is being built
|
|
# $1/temp is temp file space, $1/stage is the initramfs
|
|
# options passed on command line after that
