Basically, there's a special case in src/fsio.c which explicitly denies writing to /etc and /lib in the chroot-case, refering to 3 year old AUSCERT warnings for proftpd with FreeBSD. Someone needs to check whether those warnings still apply to current-day proftpd and freebsd. -- pi@opsec.eu +49 171 3101372 5 years to go !
