> A bug involving the interaction of 'ldconfig' and portage has been
> identified for all systems using masked libraries. Libraries that
> have been installed but are now masked in portage will be downgraded
> by portage. In versions of portage prior to 2.0.43, portage creates
> symlinks in the library directories properly for newly merged, but
> older, library. A call to ldconfig causes these symlinks to be over-
> written with what the system(ldconfig) assumes is the best, the
> highest version, and then portage procedes to remove the symlinks
> as they match how the previous version had set them. This problem
> can result in users being locked out of systems as required libraries
> are effectively disabled.
>
> AFFECTED SYSTEMS
>
> All systems using portage prior to portage-2.0.43 are succeptable.
> Systems that have installed the latest versions of libraries that
> have since been masked in portage are of major concern, and systems
> with ncurses-5.3 installed can disable logins if 'emerge -u world'
> is performed with ncurses-5.3 masked.
>
> SOLUTION
>
> Users experiencing missing library symlinks can do the following:
> # ldconfig
> # emerge rsync
> # emerge '=portage-2.0.43'
>
> If a root console is not accessable the following method may be used:
> Systems using Grub:
>   press 'e' on your kernel
>   press 'e' over your kernel line
>   append without the quotes:
>     " init=/bin/sash"
>   press enter to finish the changes
>   press 'b' to boot the kernel
> Systems using LILO:
>   at boot hold in left shift to get the prompt
>   type in your kernel's label (name)
>     You can get the list of kernel names by hitting <tab> at this point.
>   append to that label the following: ' init=/bin/sash'
>     You may also have to specify a 'root=' or other information.
>   press enter to boot the kernel
> When at the '>' prompt type the following:
>     > mount -o remount,rw /
>     > /sbin/ldconfig
>     > mount -o remount,ro
>     > reboot
>
> After running the above Grub or LILO commands, users should update to
> portage-2.0.43 as stated above for users not locked out of their consoles.
