Of course I sourced it and complains about plain.tex

binaries. 

Let's start over for the simple reason that texmfcnf.lua does not exist.

Not through a TeX Live infrastructure only installation anyway. 

let's run ./install --modules=all and it rightly reports that 

mtx-update      | updating mtxrun for linux-64: rsync -tgo --chmod=a+x
'/home/ce/context-install/tex/texmf-context/scripts/context/lua/mtxrun.lua'
'/home/ce/context-install/tex/texmf-linux-64/bin/mtxrun'
mtx-update      | run, rsync -tgo --chmod=a+x '/home/ce/context-install/tex/texmf-context/scripts/context/lua/mtxrun.lua'
'/home/ce/context-install/tex/texmf-linux-64/bin/mtxrun'
rsync: [Receiver] change_dir#3 "/home/ce/context-install/tex/texmf-linux-64/bin" failed: No such file or directory (2)
rsync error: errors selecting input/output files, dirs (code 3) at main.c(827) [Receiver=3.2.7]
resolvers       | tds | no 'texmf-linux-64' under tree '/home/ce/context-install/tex'

Now. Let's add the directories, correct? 

If you were to look at the following 

resolvers       | resolving | using configuration specification 'home:texmf/web2c;{selfautoloc:,selfautoloc:/share/texmf-local/web2c,selfautoloc:/share/texmf-dist/web2c,selfautoloc:/share/texmf/web2c,selfautoloc:/texmf-local/web2c,selfautoloc:/texmf-dist/web2c,selfautoloc:/texmf/web2c,selfautodir:,selfautodir:/share/texmf-local/web2c,selfautodir:/share/texmf-dist/web2c,selfautodir:/share/texmf/web2c,selfautodir:/texmf-local/web2c,selfautodir:/texmf-dist/web2c,selfautodir:/texmf/web2c,$SELFAUTOGRANDPARENT/texmf-local/web2c,selfautoparent:,selfautoparent:/share/texmf-local/web2c,selfautoparent:/share/texmf-dist/web2c,selfautoparent:/share/texmf/web2c,selfautoparent:/texmf-local/web2c,selfautoparent:/texmf-dist/web2c,selfautoparent:/texmf/web2c}'
resolvers       | resolving |
resolvers       | resolving | looking for regular 'texmfcnf.lua' on given path
'/home/ce/texmf/web2c' from specification 'home:texmf/web2c'
resolvers       | resolving | looking for regular 'texmfcnf.lua' on weird path
'/home/ce/context-install/tex/texmf-linux-64/bin' from specification 'selfautoloc:'


you'd notice that is looking over and over for a texmfcnf.lua 

But where is my texmfcnf.lua? Would you know? :) Because I don't. The
only instance of a texmfcnf.lua dates back to a prepackaged
installation that is no longer there anyway

it points to a prepackaged texlive which I'm not using and not planning
to. 

and what I have under TEXMFHOME which doesn't amount to much anyway , or what's
important for the current issue is 

amiga-pl.tcx  cp8bit.tcx       il2-t1.tcx    mktex.opt     tcvn-t5.tcx
cp1250cs.tcx  empty.tcx        kam-cs.tcx    mktexdir      texmf.cnf
cp1250pl.tcx  fmtutil-hdr.cnf  kam-t1.tcx    mktexdir.opt  updmap-hdr.cfg
cp1250t1.tcx  fmtutil.cnf      macce-pl.tcx  mktexnam      updmap.cfg
cp227.tcx     il1-t1.tcx       macce-t1.tcx  mktexnam.opt  viscii-t5.tcx
cp852-cs.tcx  il2-cs.tcx       maz-pl.tcx    mktexupd
cp852-pl.tcx  il2-pl.tcx       mktex.cnf     natural.tcx

which as you fully know, it doesn't help

What is TeX Live infrastructure doing is the question

It's besides the point to call out ./tlmgr install context here because
 mtx is no longer there anyway 

for what's worth
