I have the same behavior for files or even complete dirs in my linux
jails. The files are visible on the host computer (FreeBSD 9-CURRENT
amd64 with v28 ZFS root pool), but if I chroot in the linux jail (so
now it's not a jail but only a chroot running linux binaries), I can't
"ls" them. I can provide more details but I'm not in front of my
computer right now. What do you need ?
