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

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? -- David C. Rankin, J.D.,P.E.
