I've updated the PR with some short info what I found. 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.
