See the README file in the first patch of this series for
important details.
kickstart.py.patch has most of our changes to the anaconda code.
These changes include:
* an --interactive flag for pre- and post-install scripts.
That causes anaconda to allow regular "cooked" output on a
serial console terminal or the regular keyboard, video monitor
and mouse (KVM.)
* support for tape restore. We introduce a new install type,
"restore", which skips many of the regular kickstart install
steps. This enables a post-install script to re-install the
system from a backup tape.
* passing the -s command line flag for post-install scripts when
they were running on a serial console. We needed to be
prepared for a user restoring a tape from a KVM system onto a
serial console system, and vice versa. This way the post
restore script knows it may need to adjust system configuration
files for the other kind of console. This change also may
result in pre-install scripts being passed a -s flag. We only
ever tested or used -s in post-install scripts. We cannot say
for sure because our pre-install scripts do not try to process
command line flags.
