# this handler will save various reports of vital system information.
|
|
# by default, all the reports are enabled and are saved in /var/backups.
|
|
#
|
|
# (1) 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
|
|
#
|
|
# (2) 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!!!)
|
|
#
|
|
# (3) hardware information.
|
|
# a simple report is generated of the kernel modules, the devices,
|
|
# and the model of the hardware which 'discover' is able to detect.
