It seems too difficult for me. fmtutil-sys is a bash script which calls 
another bash script, fmtutil, which in turn calls a bunch of binaries 
(as results from intall-tl.log) in the form like this:

aleph -ini   -jobname=aleph -progname=aleph *aleph.ini
aleph -ini   -jobname=lamed -progname=lamed *lambda.ini
pdftex -ini   -jobname=amstex -progname=amstex -translate-file=cp227.tcx 
*amstex.ini
[...]

It seems that the binaries aleph, pdftex... are passed via a fmtutil.cnf 
configuration file.

Anyway, with a binary testing (only .dll.bz2 of snapshots), I have 
verified that the last snapshot with which the .fmt files get the right 
permissions (-rw-r--r--) is 20100904 snapshot, instead with 20100910 
they acquires wrong permissions (rwx------). In short, after >= 20100910 
  snapshot, fmtutil script creates /tmp/fmtutil.NUMBER with drwx-----+ 
permissions: fmtutil.NUMBER is a working directory for fmtutil.

This is the best I could do!

For the moment I will adopt this manual fix :(

find /usr/local/texlive/ \! -type d \! -type l -perm u=rwx | xargs chmod 
-x,go+r


Ciao,
Angelo.
