Bug Description
[Impact]
grep can't be used under udev, preventing kdump-tools to be used after a memory hotplug.
[Test case]
Run grep with systemd-run -t --property MemoryDenyWrite
[Regression potential]
The fix is a simple rebuild, so should have minimal potential for regression.
-------
# systemd-run -t --property MemoryDenyWrite
Running as unit: run-u54.service
Press ^] three times within 1s to disconnect TTY.
/bin/grep: error while loading shared libraries: cannot restore segment prot after reloc: Operation not permitted
#
Under ppc64el, grep can't be used under udev, because it restricts mapping to be Write+Execute, with MemoryDenyWrite
