=head1 SYNOPSIS

/usr/local/cpanel/scripts/post_snapshot [--yes]

B<WARNING>: This is a destructive action. If you run this script on a production
server, data loss will occur. Pass the --yes option to acknowledge that you
understand this warning. If any cPanel users are detected, further confirmation
will be required.

Updates the running system with changes needed after it starts from a snapshot,
presumably to be a different IP address and hostname.

This script will abort and exit non-zero if one or more operations attempted
during post_snapshot fail.

If this script exits nonzero when used according to the documentation, you
should consider the server potentially damaged and unusable.
