Description:
The PKGBUILD for community/ngircd 21-1 installs ngircd.service with 755 permissions (rwxr-xr-x), which is less common than 644 permissions (rw-r-r-). This appears to be extremely unimportant, but I thought I'd report it anyway. I googled around and couldn't find any official documentation on unit permissions, so here's a couple of examples of virtually the same 'problem' being patched:

* http://lists.busybox.net/pipermail/buildroot/2013-December/083920.html
* http://marc.info/?l=fedora-extras-commits&m=136876891115650&w=2 (prepare for bold eyerape)

The permissions in action:
$ ls -l /usr/lib/systemd/system/n*
...
-rw-r--r-- 1 root root 433 Mar 11 20:26 /usr/lib/systemd/system/network.target
-rw-r--r-- 1 root root 513 Mar 18 13:18 /usr/lib/systemd/system/nginx.service
-rwxr-xr-x 1 root root 216 Dec 3 03:18 /usr/lib/systemd/system/ngircd.service
-rw-r--r-- 1 root root 398 Feb 27 23:21 /usr/lib/systemd/system/nscd.service
...
$ pacman -Qo /usr/lib/systemd/system/ngircd.service
/usr/lib/systemd/system/ngircd.service is owned by ngircd 21-1
