[arch-dev-public] News item: /lib removal - Was: heads up: /lib removal

A patched version of pacman is now in [testing] that will detect all the
issues reported so far that resulted in failed updates.   Users of the
[testing] repo who last updated in the three days between the kmod
update and the glibc update may still run into issues, but "pacman -Sy
pacman && pacman -Su" will prevent that.

Here is a (very draft) news item.  I think it provides complete update
instructions for people using the "stable" repos.



Removal of /lib directory

All files in the /lib directory have been moved to /usr/lib and now /lib
is a symlink to usr/lib.  During this update, pacman will identify a
conflict in the /lib directory.  In the simplest case, this is worked
around by doing

pacman -Syu --ignore glibc
pacman -Su

When additional package depend on having a newer version of glibc than
is currently on your system and these also have files in /lib (e.g.
older versions of gcc), then and extra step will be necessary.  For example:

pacman -Syu --ignore glibc gcc
pacman -Sd gcc
pacman -Su

Only do the -Sd step if really necessary.  Pacman will warn you about a
conflict in /lib on the -Su step if it is.

If the "pacman -Su" step reports a conflict in /lib, you will need to
look at all the files in /lib and determine which ones are not owned by
glibc.  This is achieved by "pacman -Qo /lib/*".  You will need to move
any files not belong to glibc to /usr/lib (either through fixing their
package or manually moving unowned files).  There should be no
subdirectories in /lib either.

Finally, NEVER use pacman --force (-f) for the glibc update.  That will
result in a broken system.
