It may look like we're currently experiencing more stuckness, but this will
lead us to Quality. We'll have this release in the can before you know it.

Thanks to perrin4869.
a/util-linux-2.37.3-x86_64-1.txz: Upgraded.
This release fixes two security mount(8) and umount(8) issues:
An issue related to parsing the /proc/self/mountinfo file allows an
unprivileged user to unmount other user's filesystems that are either
world-writable themselves or mounted in a world-writable directory.
Improper UID check in libmount allows an unprivileged user to unmount
FUSE filesystems of users with similar UID.

default). Impact is denial of service or other undefined behavior.
While we're here, also patch a memory leak on output file opening error.
