440. Briefly: Upgrading Arch -- consolidation of /sbin, /bin and /usr/sbin

Anyone running Arch and attempting to upgrade recently will have run into this:

(83/83) checking for file conflicts  [##########] 100%
error: failed to commit transaction (conflicting files)
filesystem: /bin exists in filesystem
filesystem: /sbin exists in filesystem
filesystem: /usr/sbin exists in filesystem
Errors occurred, no packages were upgraded.

There's a solution:

What I'm doing in this post is simply testing that solution. The intellectual contribution from me is very small.

1. Non-official packages

pacman -Qqo /bin /sbin /usr/sbin | pacman -Qm -

bootchart2-git 20130314-1

Not too bad.

sudo pacman -R bootchart2-git

2. Unofficial repositories

cat /etc/pacman.conf | grep '^\['

[options]
[core]
[extra]
[community]
[multilib

OK. Let's see whether there are any packages around:

paclist options | awk ' { print $1 } ' | pacman -Ql - | grep ' /s\?bin/\| /usr/sbin/'

apache /usr/sbin/
apache /usr/sbin/ab
apache /usr/sbin/apachectl
apache /usr/sbin/apxs
[..]
wpa_supplicant /usr/sbin/wpa_supplicant
zvbi /usr/sbin/
zvbi /usr/sbin/zvbid

paclist core | awk ' { print $1 } ' | pacman -Ql - | grep ' /s\?bin/\| /usr/sbin/'
paclist extra | awk ' { print $1 } ' | pacman -Ql - | grep ' /s\?bin/\| /usr/sbin/'
paclist community | awk ' { print $1 } ' | pacman -Ql - | grep ' /s\?bin/\| /usr/sbin/'
paclist multilib | awk ' { print $1 } ' | pacman -Ql - | grep ' /s\?bin/\| /usr/sbin/'

I think 'options' would qualify as an Official repository, so we are fine.
3. Orphan packages

find /bin /sbin /usr/sbin -exec pacman -Qo -- {} + >/dev/null

comes up blank. Good.

4. Upgrade

sudo pacman -Syu --ignore filesystem,bash
