[syslog-ng] composing file names with system varible

[peceka]

Hi,

i've on my machine file with some name, for example:
# cat /var/hostname
smeagol

now i want to have log files like this:
/var/log/smeagol-all.log

if i change content of /var/hostname and then restart syslog-ng,
syslog-ng shoud start logging to files with new name.

is it possible? mabye no directly but with some workaround?

regards,
p.
