I understand, I just wanted to say that most other build systems ignore 
the umask, for example here is a build script (after running "make 
install") of a program named astmkprof (which uses GNU Autoconf and GNU 

     libtool: install: /usr/bin/install -c astmkprof 
      /usr/bin/mkdir -p '/usr/local/etc'
      /usr/bin/install -c -m 644 astmkprof.conf '/usr/local/etc'
      /usr/bin/mkdir -p '/usr/local/share/man/man1'
      /usr/bin/install -c -m 644 astmkprof.1 '/usr/local/share/man/man1'

Before install this was the long listing for astmkprof:

    $ ls -l astmkprof
    -rwx------ 1 myuserid myuserid 3743200 Mar 12 13:26 astmkprof

After install it is:

    $ ls -l /usr/local/bin/astmkprof
    -rwxr-xr-x 1 root     root      3743200 Mar 12 13:27 astmkprof

You can see that the GNU Build system (which is widely used by nearly 
all users of GNU/Linux distributions and other OSs) explicitly sets the 
permission bits on install and does not rely on the value of umask (you 
can see that its default is "rwxr-xr-x"). As you can see, it also does 
this for the man page. Infact from the manual of GNU Coreutils, this is 
the whole purpose of the "install" program, otherwise the build script 
would simply have used "cp".

So my question is that while most other components of the operating 
system (which use Autoconf and Automake) don't rely on or ignore the 
"permissions that root has set via umask", why does Tex live rely on it?

I understand that it might be an internal convention for Texinfo, I just 
don't understand its relevance given that other major programs ignore umask.

Thank you very much,
