使用 pacman -Syu 更新時，出現下面的警告訊息

warning: uboot-cubieboard2: ignoring package upgrade (2014.04-8 => 2014.04-10)
there is nothing to do[@more@]看起來似乎是 linux-firmware / linux-sun7i / uboot-cubieboard2 這三個套件被設定成不能夠更新
# grep IgnorePkg /etc/pacman.conf
# Pacman won’t upgrade packages listed in IgnorePkg and members of IgnoreGroup
IgnorePkg = linux-sun7i linux-firmware uboot-cubieboard2
原來是這一個 ArchLinux 的版本有設定這三個套件不做更新。
因為我目前用的這一個版本是特別製作給 BerryBoot 使用的版本，所以不是很了解，為什麼要特別限定這三個套件不做更新！
