Subject: (main): Don't set the umask to 0 and hand-apply
X-Git-Tag: TEXTUTILS-2_0_8~94
X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=beebc6916806d148b3e38a4f61d4455fd6486aa2;p=thirdparty%2Fcoreutils.git

(main): Don't set the umask to 0 and hand-apply
the previously-set umask unconditionally.  Do that only when a
MODE has been specified.  Otherwise, call mknod with the full
creation mask (0777 or 0666) and let the kernel apply the umask.
The difference shows up only on file systems with ACL support
when the containing directory has a default ACL.
Patch by Andreas Gruenbacher.
(main): Rename local `symbolic_mode' to `specified_mode'.
Also, when MODE is specified, call chmod to ensure that the
permission bits are set as specified even when the containing
directory has a default ACL.
