# 2003 01 08: We now age the output from rpm -VA to make back
# comparisons easier.
# The loop that creates directories now has the -p option for mkdir,
# which means you can create parents on the fly if they don't already
# exist.
# initrd is now in the list of directories to create automatically.
# We now exclude more stuff when building the tarballs.
# 2002 07 01: Went to bzip2 to compress the archives, for smaller
# results. This is important in a 100MB ZIP disk. Also some general
# code cleanup.
# 2002 07 01: The function crunch will tar and BZIP2 the
# archives. This is cleaner than the old code, and has better safety
# checking.

# Crunch: A function to compress the contents of a directory and put
# the archive onto the ZIP disk.
# The first parameter is the name of the archive file to be
# created. The backup location, $zip, will be prepended and the
# extension, "tar.bz2" will be appended.
# All following parameters will be taken as additional directories or
# files to be put into the archive.

then
echo "-Parameter #1 or #2 is missing.-" # Also if no parameter is passed.

shift # Discard the file name
local dirs=$@ # The director[y|ies] to archive
local tarcmd="tar -cjf" # The tar command.

error=$? # Preserve the exit code

# Now we save hard drive information. Run make.fdisk on each hard
# drive in the order in which it mounted from the root partition. That
# is, run it first on the hard drive with your root partition, then
# any hard drives that mount to the first hard drive, then any hard
# drives that mount to those. For example, if your root partition is
# on /dev/sdc, run "make.fdisk /dev/sdc" first.
# The reason for this is that make.fdisk produces a script to make
# mount points and then mount the appropriate partition to them during
# first stage restore. Mount points must be created on the partition
# where they will reside. The partitions must be mounted in this
# order. For example, if your /var and /var/ftp are both separate
# partitions, then you must mount /, create /var, then mount /var,
# then create /var/ftp. The order in which the script "first.stage"
# runs the mounting scripts is based on their time of creation.
# If necessary, put a line, "sleep 1" between calls to make.fdisk.
