<define name="blacklist">
<a:documentation>
The "blacklist" is a list of packages that will be *removed* if found
during an upgrade. Typically this is used to handle tricky upgrade cases
that can't be modeled with existing RPM Obsoletes/Conflicts/etc.
Here's an example: In FC6, hal was a multilib package, but in F7 we split
it into (non-multilib) hal and (multilib) hal-libs.
So the system starts with hal.x86_64 and hal.i386 (for multilib compat).
We want to upgrade to hal.x86_64 and hal-libs.x86_64, with hal-libs.i386
for multilib. Upgrading hal.x86_64 will bring in hal-libs.x86_64, and
upgrading hal.i386 brings in hal-libs.i386. Adding a blacklist item for
'hal.i386' causes anaconda to remove the (now-unneeded) hal.i386,
which gives us the desired outcome.

Arch to blacklist this package from. If unspecified, it will be

<define name="whiteout">
<a:documentation>
The RPM "whiteout" list is used to by RPM to break dependency loops.
Each "ignoredep" element has two attributes - "package" and "requires" -
which are both package names. While calculating dependencies, RPM will
ignore any dependency that results in p requiring r.
This is used to keep upgrades from getting stuck on known dependency loops,
like with mutually dependent packages (e.g. xinitrc and xorg-x11)
To feed this info to RPM, each item should be converted to a string of the
form 'package>requires', and the RPM macro '_dependency_whiteout' should be
filled with a (whitespace-separated) list of these items.
