within PCA.

> Some background: The kernel patch 120011 requires 125547, which requires
> 122660. This second requirement is not listed in the patchdiag.xref; it is
> checked only during installation of the patch in a prepatch script. So pca
> adds 122660 to the list of required patches for 125547 as a first step. Next
> issue: 122660 is obsoleted by 120011. This is a circular patch dependency
> (which is the reason why Sun didn't add 122660 to the required patches
> list). I'm breaking that by un-obsoleting 122660, so pca will show it in the
> list of patches to be installed. But 122660 requires some other patches
> itself. Some of them are obsoleted by 120011 *again*, so I have to break
> this dependency loop by un-obsoleting those patches as well.

> The net effect is that pca should now list, download and install all the

> This is the solution recommended by Sun as well. They also implement this
> workaround in their Traffic Light Patching (TLP) system, so it's safe.

> The same problem exists on i386 with 120012/120661; it's fixed as well.
