The make install script, which most users would run via sudo to install into /usr/local, will use the current umask of the root user when creating certain files and directories. If one uses a restrictive umask by default (e.g. umask 077), this means that only the root user will be able to use the full Bitcoin package.
Expected behavior
The install script creates all directories and files, including man pages, etc., with permissions 644 / 755.
Actual behavior
Certain folders are created using the default umask, e.g.:
- /usr/local/share/man/man1/
- /usr/local/lib/pkgconfig/
- [...]
This means that only root can access files in these folders and other users won't be able to read the man pages (for example).
To reproduce
$ ./autogen.sh
$ make
$ sudo -iu root
% umask 077
% make install
