Comment # 1 on bug 1191251 from Hagen Buliwyf

Same happened to me last weekend. My brand new theme was gone!

The reference change in /etc/default/grub might be acceptable but the deletion
of a user-created directory (without any real need!) ...


And another thing i discovered:

"Normal" packages create .rmpnew or .rpmsave files when they change user edited
configuration files.

The update of grub2-brandig-openSUSE did not create /etc/default/grub.rpmsave
but /etc/default/grub.old which will not be discovered by rpmconfigcheck.
