Details

if you for example fetch an aif package from build.archlinux.org/pkg, and try to install it with `pacman -U aif`,
you get: "cannot remove /usr/share: permission denied"

which is weird:
1) it shouldn't remove /usr/share (maybe it means /usr/share/aif)
2) /usr or /usr/share is no separate mountpoint. / is mounted rw.

i've also read reports from other people somewhere, that basically `pacman -U` operations often fail, even though the entire / should be rw
This task depends upon

Is /usr/share empty at this point? I believe pacman removes empty dirs on removal, and recurses upward. So if it removed /usr/share/aif and /usr/share was empty, it would try to remove it.

Does this actually CAUSE any errors? Or is it just a message that is weird?

Try doing "touch /usr/share/.dummy" and then pacman -U the package.

I can infer that you are using the dual iso. Oops! and this is and issue: Since /usr/share (and /lib/modules) is a bind mount, the overlay in / via aufs does not take any effect. I guess that we need to append /usr/share (and /lib/modules) to aufs stack in some way.

mmm one way to stack/append to aufs tree, is how squashfs images for /usr/share and /lib/modules are constructed. These images should contain the full path "/usr/share" and "/lib/modules" and under isomounts files, instead of putting the full path "/usr/share" must be "/", so this squashfs image will be appended to aufs stack instead of a bind mount. (in this way, was done originaly in first draft of archiso2dual)

I will see what I can do ;)
