[arch-general] pacman -Syu fails due to conflict with mtab?

[David C. Rankin]

Guys,

  Just a quick question. Upgrade failed due to conflict with mtab:

<snip>
(67/67) checking for file conflicts
[#######################################] 100%
error: failed to commit transaction (conflicting files)
filesystem: /etc/mtab exists in filesystem
Errors occurred, no packages were upgraded.

  How should I handle this? I don't think it would be a good idea to replace an
active mtab with --force. What say the experts?
