# this handler will save various reports of vital system information.

# by default, all the reports are saved in /var/backups.
|

#
|
|
# (1) a capture of the debconf package selection states. This file
|
|
# can be used to restore the answers to debconf questions for
|
|
# packages that you will be installing through (2) below. To
|
|
# do this, run: "debconf-set-selections < debconfsel.txt"
|
|
#
|
|
# (2) a list of all the packages installed and removed.
|
|
# this file can be used to restore the state of installed packages
|
|
# by running "dpkg --set-selections < dpkg-selections.txt and
|
|
# then run "apt-get -u dselect-upgrade". If you have the
|
|
# debconf-set-selections file from (1), you should restore those first.
|
|
#
|
|
# (3) the partition table of all disks.
|
|
# this partition table can be used to format another disk of
|
|
# the same size. this can be handy if using software raid and
|
|
# you have a disk go bad. just replace the disk and partition it
|
|
# by running "sfdisk /dev/sdb < partitions.sdb.txt"
|
|
# (MAKE SURE YOU PARTITION THE CORRECT DISK!!!)
|
|
#
|
|
# (4) hardware information.
|
|
# write to a text file the important things which hwinfo can gleen.
|
|
#
|
|
# (5) the LUKS header of every LUKS block device, if option luksheaders
|
|
# is enabled.
|
|
# in case you (have to) scramble such a LUKS header (for some time),
|
|
# and restore it later by running "dd if=luksheader.sda2.bin of=/dev/sda2"
|
|
# (MAKE SURE YOU PASS THE CORRECT DEVICE AS of= !!!)
|
|
#
|
|
# (6) LVM metadata for every detected volume group, if "lvm = yes"
|
|
#
|
|
# (7) a copy of each device's MBR, if "mbr = yes". A master boot record
|
|
# (MBR) is the 512-byte boot sector that is the first sector of a
|
|
# partitioned data storage device of a hard disk. To restore the MBR
|
|
# one could do something like: dd if=sda.mbr of=/dev/sda
|
|
# (MAKE SURE YOU PASS THE CORRECT DEVICE AS of= !!!)
|
|
# WARNING: Restoring the MBR with a mismatching partition table will
|
|
# make your data unreadable and nearly impossible to recover
|

# (8) a copy of the BIOS, if "bios = yes" and flashrom is installed
