Comment # 12 on bug 1143125 from Franck Bui

Martin, I've been told that you might help to figure out why in this specific
case setfont(8) fails to execute gzip.

Sum-up: setfont(8) is spawned by a udev worker which is run from udev service
which has MemoryDenyWriteExecute=yes. Basically this security option prevents
services to execute data, please see man systemd.exec(5) for a full description
of this option.

It appears that this option has a negative side effect when setfont(8) tries to
run "gzip -d ..." but I don't see why especially since this issue is only
happening here and I couldn't reproduce it.

Do you have an idea how this could be debugged further so we can understand why
MemoryDenyWriteExecute=yes has a bad effect in this specific case ?

Thanks.
