yeeah thats really bad behaviour from logtail, corrected in cvs:
$ src/logtail 
 No logfile to read. Use -f switch.

will be in next version of logtail.

never the less fiaif uses the -f switch,
but don't use the -o switch from logtail for the offset file.
there for i'm duplicating the bug to fiaif.
uups logtail(8) misses the switch in the intro,
i'll correct that too for the next release.
belows patch should help fiaif-scan.

a++ maks
