So here's what I've got for a TODO so far to get ConTeXt working on Alpine Linux with musl (subject to item #6, mtx-context.lua not being found):

1. Add the musl test to first-setup.sh
2. Add the same musl test to tex/setuptex
3. Add texlua (and texluac?) to
  a. the setup rsync bin/ directories
  b. the tex/texmf-linuxmusl(|-ppc|-64)
4. Update mtxrun

Here's code that ought to work for detecting musl in mtxrun.  Around line 3721 of the mtxrun add:

    if find(architecture,"x86_64",1,true) then
      platform="linux-64"
    elseif find(architecture,"ppc",1,true) then
      platform="linux-ppc"
    else
      platform="linux"
    end
+   if resultof("ldd --version 2>&1"):find("musl") ~= nil then
+     platform = platform:gsub("linux", "linuxmusl")
+   end 

5. Note that in tex/setuptex, there's evidently no way to get the current script so one has to explicitly provide the TeX directory (appears to be a BusyBox bug).
6. `context` is unable to locate `mtx-context.lua`.  Some tracker output sheds some light:
  i. context --trackers=resolvers.expansions is identical
  ii. context --trackers=resolvers.details,resolvers.details differs, with the output attached.  Note that to keep the comparison short I removed lines that differed only because `linux` had been changed to `linuxmusl`.

Will keep plugging away to see if I can determine why `mtx-context.lua` cannot be found on Alpine Linux.

Thanks for reading.
