Having a logfile that doesn't end in ".log" is pretty gross IMHO
Agreed.
and will mean it isn't caught by logrotate matching *.log
I did not realize that.
Can't we deal with the clash in another way that preserves .log as a
suffix
Not in the same directory, but I can create a separate directory,
something like:
/var/log/libvirt/qemu/vhost-user/%{name}-fs-%{alias}.log
/var/log/libvirt/qemu/devices/%{name}-fs-%{alias}.log
/var/log/libvirt/qemu/fs/%{name}-%{alias}.log
Or we can just pretend this is fine O:-)
