[OE-core] [PATCH V2 0/6] Avoid overwritting editable files during package updating

[Jian Liu]

For example, if updating base-files with a new version of rpm, the file 
/etc/nsswitch.conf which is created by base-files will be substituted by a new file.

This is not what we want since our configuration may be lost after updating. 

A resolution is to revise spec file of rpm and put %config before config files 
like "%config /etc/nsswitch.conf".

Theoretically all editable files should be protected with "%config". But currently 
we only concern about the following packages:
  base-files
  initscripts
  logrotate
  lvm2
  libpam
  nfs-utils
