• Cross build and packaging

  Introduction Let’s start by clarifying what we mean by cross-building and cross-packaging. Cross-compilation is the process of compiling source code on one platform, called the host, in order to generate an executable binary for a different target platform. The emphasis here is on the word “different”. The target platform may have a different CPU architecture, such as when we work on an x86 computer and want to build software for a Raspberry Pi board with an ARM CPU.

• Support distro name change from EasyOS in woofQ

  I posted to the forum about changing the name of "EasyOS" and "Easy" to something else, such as "WaryOS" and "Wary":

  There is fundamental problem with implementing that though, as the text "EasyOS" and "Easy" is hard-coded in woofQ, right from creation of EasyOS in early 2017.
  

  I thought about replacing all occurrences of those text strings with variables, and wherever there is $(gettext " ... EasyOS ...") replace with something like $(eval_gettext " ... \${NEWDISTRONAME} ...")
  However, that is very complicated to implement, a huge amount of work and likelihood of something going wrong.
