+= Boot parameters =
+
+The file README.bootparam of the mindi package provides all the parameters one can use at boot time during a MondoRescue restoration.
+
+== pre and post parameters ==
+
+In 2.2.9, mindi introduced 2 new parameters at boot prompt, pre and post.
+They are used to respectively launch a script just before launching mondorestore, and after its execution.
+
+The main goal is to allow for the pre option to configure for example the HDD layout differently, and to re-configure the systems (static IP address e.g.) for the post option.
+
+If the mastering of the target systems is regular, you can even create a /etc/mindi/mindi.conf configuration file on the master, which could redefine the MINDI_ADDITIONAL_BOOT_PARAMS variable of mindi like this:
+{{{
+cat >> /etc/mindi/mindi.conf << EOF
+MINDI_ADDITIONAL_BOOT_PARAMS="devfs=nomount noresume selinux=0 barrier=off udevtimeout=10 pre=/tmp/isodir/pre.sh post=/mnt/RESTORING/tmp/post.sh"
+EOF
+}}}
+Of course, these params can be passed at the boot prompt.
+
+And the scripts could contain as an example:
+{{{
+cat > /path/to/nfs/pre.sh << EOF
+sed -i -e "/vg02/ d" /tmp/mountlist.txt
+sed -i -e "/vg03/ d" /tmp/mountlist.txt
+EOF
+cat > /tmp/post.sh << EOF
+mount /proc
+mount /sys
+vgcfgrestore vg02
+vgcfgrestore vg03
+sed -i -e "s/IPADDR=.*/IPADDR=x.y.z.t/" /mnt/RESTORING/etc/sysconfig/network-scripts/ifcfg-eth0
+EOF
+}}}
+
+Of course, those scripts couls makemore dynamic requests to improve the resulting deployment.
