I've run into this strange problem that if I use opkg to install
mgetty then the files in /etc/mgetty+sendfax/ get set with the
correct permissions (0600). However if I build mgetty into the image
and do a clean flash then the permissions revert to providing read and
write permissions to non root users. That is a problem because mgetty
refuses to accept logins if the login.config file in that directory is
read or writeable by normal users.
The mgetty makefile has the correct "install -m600" command. I have
also tried created postinst scripts which do not fix the problem. The
package is fine if installed afterwards - but not if it is built into
the image.
It appears that this might be related to Sergey's findings below
regarding the default permissions of files. I could change 0755 to
0600 but not sure what havoc that could cause. Other than putting
in a kludge to chmod every time the system boots - am at a loss
