I mounted an iso on the filesystem using mdconfig. I then mounted an
.img file (msdos) from within that mount on its own mount .
I cd'd to the mounted directory, ran ls twice and the system crashed.
No forensics in /var/log/messages either.
any ideas? interesting at best.
mockbsd# mdconfig -a -t vnode -f bbc-2.1.iso -u 1
mockbsd# mount -t cd9660 /dev/md1 /img
mockbsd# mdconfig -a -t vnode -f /img/lnx.img -u 2
mockbsd# mount -t msdos /dev/md2 /mnt
mockbsd# ls
copy.txt linux prob.txt syslinux.cfg
inspired.txt main.txt req.txt what.txt
ldlinux.sys memtest.gar root.bin
mockbsd# ls
<boom>
mockbsd# uname -a
