+febootstrap - Bootstrap a basic Fedora system
+by Richard W.M. Jones (rjones@redhat.com)
+----------------------------------------------------------------------
+
+febootstrap is a Fedora equivalent to Debian's debootstrap.  You can
+use it to create a basic Fedora filesystem.
+
+There are currently some restrictions compared to debootstrap.
+
+For instructions, restrictions, examples etc. please read the manpage
+febootstrap(8).
+
+Requirements
+------------
+
+  fakeroot
+    - Tested with version 1.11.
+
+  fakechroot > 2.8 or 2.8 + patch
+    - NB. KNOWN NOT TO WORK WITH 2.8.  You MUST apply the patch
+      'fakechroot-2.8-relchroot.patch' to the fakechroot sources
+      and recompile.  Hopefully this patch will be included in
+      future versions of fakechroot.
+
+  yum
+    - Tested with version 3.2.
+    - Needs network access to a Fedora repository, or a local
+      Fedora mirror.
+
+  perldoc
+    - This is just used to generate the manpage.
+
+  bash
+
+Building and installing
+-----------------------
+
+  ./configure
+  make
+  sudo make install
+
+Feedback and bugs
+-----------------
+
+Send feedback to rjones@redhat.com.  You can file bugs in
+http://bugzilla.redhat.com/

+=head1 NAME
+
+febootstrap - Bootstrap a basic Fedora system (like Debian debootstrap)
+
+=head1 SYNOPSIS
+
+ febootstrap [--options] REPO TARGET [MIRROR]
+
+=head1 EXAMPLES
+
+ febootstrap fedora-10 /tmp/f10
+ febootstrap rawhide /tmp/rawhide
+ febootstrap rawhide /tmp/rawhide http://mymirror/rawhide/x86_64/os
+ febootstrap --groupinstall="Mail Server" rawhide /tmp/rawhide
+
+=head1 DESCRIPTION
+
+febootstrap creates a Fedora root filesystem, based on the Fedora
+version specified by I<REPO> under the directory specified by
+I<TARGET>.  Optionally I<MIRROR> can point to a local mirror
+(otherwise the public Fedora mirrors are used).  I<REPO> names are
+C<fedora-I<VERSION>> (eg. C<fedora-10>) or C<rawhide>.
+
+febootstrap does not need to be run as root.  If for some reason you
+do run it as root, then it works slightly differently and may have
+side effects such as stopping or starting system daemons.
+
+For more advanced needs, take a look at L<mock(1)> and
+C<livecd-creator>.
+
+The normal output is a root directory located at I<TARGET> and
+a fakeroot logfile at C<I<TARGET>/fakeroot.log>.
+
+=head1 OPTIONS
+
+=over 4
+
+=item B<--install="list of packages separated by commas">
+
+=item B<--groupinstall="list of groups separated by commas">
+
+Specify the list of packages or groups to install.  These are passed
+directly to C<yum install> or C<yum groupinstall> commands, and thus
+any dependencies are also resolved by yum.  You can also use shell
+globs and filenames here, as with ordinary yum.
+
+If no packages or groups are given, then we install the C<Core> group
+which is the smallest working Fedora installation.  Use C<yum
+groupinfo Core> to list the packages currently in the C<Core> group.
+
+=back
+
+=head1 FAKEROOT LOGFILE
+
+When febootstrap is run as non-root (the normal case) we use fakeroot
+so that yum thinks it is running as root.  Fakeroot keeps track of
+"real" file permissions in a log file which is saved into the target
+directory as C<I<TARGET>/fakeroot.log>.
+
+You can use the fakeroot logfile in a number of ways:
+
+=over 4
+
+=item *
+
+Run C<fakeroot -i fakeroot.log I<command>> in order to run a
+command with the faked file permissions.
+
+=item *
+
+Generate an initrd (cpio) file containing the correct permissions
+using the tool C<febootstrap-to-initrd>.
+
+=item *
+
+Apply the permissions to the target directory using the tool
+C<febootstrap-fix-root> (requires root).
+
+=back
+
+=head1 COMPARISON TO debootstrap
+
+febootstrap cannot do cross-architecture installs (C<debootstrap
+--foreign>).  The reason is that C<%pre> and C<%post> scripts cannot
+run.  It may be possible to defer running of scriptlets (which is
+basically how debootstrap works), and patches to do this are welcomed.
+
+febootstrap cannot do 32-on-64 bit installs.  The reason is that
+fakeroot and fakechroot do not load the correct preload library.  This
+is really a bug in fakeroot/fakechroot, which we think would be easy
+to fix.  (debootstrap deals with this case the same as for
+C<--foreign> installs - see previous point).
+
+=head1 OTHER RESTRICTIONS AND BUGS
+
+Some C<%post> scripts do not run correctly.  The most common case is
+C</sbin/ldconfig>.  Since this binary is statically linked, fakeroot
+and fakechroot's LD_PRELOAD hack does not work, so effectively
+ldconfig tries to update the system cache.  You will see the following
+error:
+
+ /sbin/ldconfig: Can't create temporary cache file /etc/ld.so.cache~: Permission denied
+
+This error is mostly harmless.  Just run C</sbin/ldconfig> the first
+time you boot into the newly created Fedora system.
+
+Another error you will see is with C</usr/sbin/glibc_post_upgrade>
+which is caused for the same reason - this binary is statically
+linked.  We have examined what this binary does, and it is not really
+necessary for installs.  If it makes you happier, you can run it the
+first time you boot the new system.
