ftpd does things in this order:

openlog(..)

chroot(...)

syslog(...)

So we could think that, as openlog is done before chroot, syslog would work.

It doesn't. Though in theory it should.

No hard or soft links solved the problem. The way to fix this is to

have an own syslog(3) which does syslog by using UNIX domain IPC.

You can get syslog.c from uunet.uu.net:/bsd-sources/lib/libc/syslog.c

and then do the changes.
