Wouldn't that revert the whole of portage, not just the parts affecting
ldap, W and the rest? All of a sudden emerge world wants to downgrade
previously upgraded programs, some of which may have been updated for
security reasons. This means the user has to go through the Changelogs,
ebuild and package.mask to find out why they are being downgraded and
whether to apply the downgrade. this would be far more work that package
masking a few updates dependent on W, which could probably be scripted.
Yes, it would revert the whole portage, and that would be desired, so
as to be up quickly. It could potentially take hours to figure out
which packages are being affected by a broken updated package.
But, perhaps it would be better to write a utility that will downgrade
a package, as well as all dependencies. Or does this already happen
when you downgrade?
