I have no TEX.. variable set :
danjean@atsina:~$ sudo su
root@atsina danjean# export | grep TEX

And still the different behavior weather KPSE_DOT is set or not :
root@atsina danjean# kpsewhich --expand-var='$TEXMFCNF'
{/usr/bin,/usr,/}{,{/share,}/texmf{-local,}/web2c}::/usr/share/texmf/web2c:/usr/share/texmf/web2c
root@atsina danjean# export KPSE_DOT="/users/huron/danjean"
root@atsina danjean# kpsewhich --expand-var='$TEXMFCNF'
/users/huron/danjean/texmf.cnf: Permission denied
{/usr/bin,/usr,/}{,{/share,}/texmf{-local,}/web2c}::/usr/share/texmf/web2c:/usr/share/texmf/web2c

For my personnal information, what is the real problem ?
1) KPSE_DOT should not be set to PWD in fmtutil ?
2) kpsewhich should not look at $KPSE_DOT directory ?
3) other ?

  Best regards,
