Ok. Finally had to read luatools.lua.

MTX_INPUT_TRACE=10 luatools --generate gives a bit more info.

This is what I think is happening. I do sudo mktexlsr and get
mktexlsr: Updating /usr/local/share/texmf/ls-R... 
mktexlsr: Updating /var/lib/texmf/ls-R-TEXMFMAIN... 
mktexlsr: Updating /var/lib/texmf/ls-R-TEXLIVE... 
mktexlsr: Updating /var/lib/texmf/ls-R... 
mktexlsr: Done.

ls-R-TEXMFMAIN and ls-R-TEXLIVE and symlinked in other directories. But no ls-R
was created for TEXMFHOME. Luatools looks in directors in TEXMF containing ls-R
files. It does not find any in $HOME/texmf, so it does not include it in the
hash for where to look for files. When it searches for cont-en.tex it finds one
in /usr/share/texmf/ (the distribution directory).

kpsewhich on the other hand (it appears) also searches files in the TEXMF 
tree. This is what kpsewhich tells me

kdebug:Search path for ls-R files (from texmf.cnf)
kdebug:  = 
/var/lib/texmf:/usr/local/share/texmf:/usr/share/texmf:/usr/share/texmf-texlive

kdebug:Search path for tex files (from texmf.cnf)
kdebug:  = 
.:/home/adityam/.texmf-config/tex/kpsewhich//:/home/adityam/.texmf-var/tex/kpsewhich//:/home/adityam/texmf/tex/kpsewhich//:/etc/texmf/tex/kpsewhich//:!!/var/lib/texmf/tex/kpsewhich//:!!/usr/local/share/texmf/tex/kpsewhich//:!!/usr/share/texmf/tex/kpsewhic
h//:!!/usr/share/texmf-texlive/tex/kpsewhich//:/home/adityam/.texmf-config/tex/generic//:/home/adityam/.texmf-var/tex/generic//:/home/adityam/texmf/tex/generic//:/etc/texmf/tex/generic//:!!/var/lib/texmf/tex/generic//:!!/usr/local/share/texmf/tex/generic/ 
/:!!/usr/share/texmf/tex/generic//:!!/usr/share/texmf-texlive/tex/generic//:/home/adityam/.texmf-config/tex///:/home/adityam/.texmf-var/tex///:/home/adityam/texmf/tex///:/etc/texmf/tex///:!!/var/lib/texmf/tex///:!!/usr/local/share/texmf/tex///:!!/usr/shar 
e/texmf/tex///:!!/usr/share/texmf-texlive/tex///


So /home/adityam/texmf/tex/// tree is there, and it seems that kpsewhich finds
the file by brute-force search of that tree (there is no ls-R file in
TEXMFHOME).

So, I read the man page of mktexlsr and try
mktexlsr $HOME/texmf

which creates a ls-R in $HOME/texmf

Now, I recreate the formats, and finally things are working. That is, I am back
to where I was before I reinstalled the OS. Mkiv is working, mtxrun --script
font still does not work. I will look into that tomorrow.

Bottom line, if you try to install mkiv on a non-distribution tree, run mktexlsr
<tree> before generating formats.
