# (1) a capture of the debconf package selection states. This file
|

# packages that you will be installing through (2) below. To

# (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"
