# rear contains only bash scripts plus documentation so that on first glance it could be "BuildArch: noarch"
# but actually it is not "noarch" because it only works on those architectures that are explicitly supported.
# Of course the rear bash scripts can be installed on any architecture just as any binaries can be installed on any architecture.
# But the meaning of architecture dependent packages should be on what architectures they will work.
# Therefore only those architectures that are actually supported are explicitly listed.
# This avoids that rear can be "just installed" on architectures that are actually not supported (e.g. ARM or IBM z Systems):
ExclusiveArch:  %ix86 x86_64 ppc ppc64 ppc64le
# Furthermore for some architectures it requires architecture dependent packages (like syslinux for x86 and x86_64)
# so that rear must be architecture dependent because ifarch conditions never match in case of "BuildArch: noarch"
# see the GitHub issue
%ifarch %ix86 x86_64
Requires:       syslinux
# In the end this should tell the user that rear is known to work only on x86 x86_64 ppc ppc64 ppc64le
# and on x86 x86_64 syslinux is explicitly required to make the bootable ISO image
# (in addition to the default installed bootloader grub2) while on ppc ppc64 ppc64le the
# default installed bootloader yaboot is also useed to make the bootable ISO image.
BuildRoot:      %{_tmppath}/%{name}-%{version}-build
# LSB RPM Requires:
# Begin of "Requires: lsb" cleanup:
# Rear upstream has "Requires: lsb" but that requires much too much,
# see
# "A distribution is LSB Certified or LSB compliant if and only if
#  the distribution provides all requirements as outlined in the
#  specification."
# Accordingly SUSE's lsb RPM requires tons of stuff that is not
# needed by Rear (in particular various graphical libraries,
# sound stuff, printing stuff, and so on).
# Therefore "Requires: lsb" is replaced by explicitly listing the RPM packages
# that are mandatory (in particular when a binary is called in a script) for Rear (as RPM Requires)
# plus what seems to be optional (nice to have) for Rear (as RPM Recommends)
# minus library packages because needed libraries should be automatically required.
# I <> think requiring RPM packages instead of binaries is better
# because it keeps the list shorter which is hopefully easier to maintain and
# the requirements are on a more higher level which is hopefully more unsusceptible against
# minor changes in what exact binaries names are actually called by Rear.
# To test if a binary is called by a Rear script the following was done (example for /usr/bin/bc):
#   BIN="bc"
#   for f in $( find /usr/share/rear/ )
#   do grep "\<$BIN\> " $f 2>/dev/null | grep -v '^[[:space:]]*#'
#   done
# What is not tested to find out if a binary is called by a Rear script is "eval" stuff,
# something like STRING=<result of whatever calls> ; eval $STRING
# Usually Rear calls "eval echo ..." or "eval "${EXTERNAL_whatever[@]}"
# except in /usr/share/rear/finalize/default/ that calls
#   eval "$(scsi_id ...
# where the only scsi_id that I could find is /usr/lib/udev/scsi_id
# which belongs to udev and I assume that udev is installed in any case
# so that there is no explicit RPM Requires for udev in Rear.
# What is also not tested to find out what Rear actually needs is
# which files (not only binaries) Rear needs to build up its recovery system
# (in particular tools for partitioning, creating filesystems, and bootloader installation).
# I assume what Rear needs to build up the system-specific recovery system is installed
# (e.g. if the ext4 filesystem is used, I assume mkfs.ext4 is installed)
# so that there are no explicit RPM Requires needed for that in Rear.
# The following list was derived from the RPM Requires of SUSE's lsb package
# (its last RPM changelog entry dated "Tue Oct  1 07:01:56 UTC 2013") as follows:
#   for r in $( grep ^Requires: lsb.spec | tr -s ' ' | cut -d ' ' -f2 )
#   do rpm -q --whatprovides $r
#   done | sort -u
# which results the following list where only what is needed for Rear is activated:

Relax-and-Recover (abbreviated rear) is a highly modular
disaster recovery framework for GNU/Linux based systems,
but can be easily extended to other UNIX alike systems.
The disaster recovery information (and maybe the backups)
can be stored via the network, local on hard disks or
USB devices, DVD/CD-R, tape, etc. The result is also a
bootable image that is capable of booting via PXE,
DVD/CD and USB media.

Relax-and-Recover integrates with other backup software
and provides integrated bare metal disaster recovery
abilities to the compatible backup software.

Warning for users who like to upgrade Relax-and-Recover:
Users who already use it must re-validate that their
particular disaster recovery procedure still works.
See in particular "Version upgrades" at

Additionally when you already use Relax-and-Recover and
you upgrade software that is related to the basic system
(e.g. kernel, storage, bootloader, init, networking) or
you do other changes in your basic system, you must also
re-validate that your particular disaster recovery
procedure still works for you.
