Previously, when the destination file was created with fopen, we needed to use fchmod to set its permissions. Now that we pass in the mode to creat, we already get the desired behavior of creating the file with the same mode as the source file modified by the user's file creation mask. This fixes the issue where a directory or special file created with mkdir/mknod does not end up with the appropriate mode with -p or -a (since it may have been narrowed by the umask). This also allows us to clear the SUID and SGID bits from the mode if the chown fails, as specified by POSIX.
sbase - suckless unix tools
===========================
sbase is a collection of unix tools that are inherently portable
across UNIX and UNIX-like systems.
The following tools are implemented:
'#' -> UTF-8 support, '=' -> Implicit UTF-8 support, '*' -> Finished,
'|' -> Audited, 'o' -> POSIX 2013 compliant, 'x' -> Non-POSIX,
'0' -> NUL handling, '()' -> Petty flag

The complement of sbase is ubase[1] which is Linux-specific and
provides all the non-portable tools. Together they are intended to
form a base system similar to busybox but much smaller and suckless.
Building
--------
To build sbase, simply type make. You may have to fiddle with
config.mk depending on your system.
You can also build sbase-box, which generates a single binary
containing all the required tools. You can then symlink the
individual tools to sbase-box or run: make sbase-box-install
Ideally you will want to statically link sbase. If you are on Linux
we recommend using musl-libc[2].
Portability
-----------
sbase has been compiled on a variety of different operating systems,
including Linux, *BSD, OSX, Haiku, Solaris, SCO OpenServer and others.
Various combinations of operating systems and architectures have also
been built.
You can build sbase with gcc, clang, tcc, nwcc and pcc.
