 No. df require `/emul/linux/proc' to be mounted, because of
 `/emul/linux/etc/mtab'.
 
 njoly@cixy [~]> ls -l /emul/linux/etc/mtab 
 lrwxr-xr-x  1 root  wheel  31 Mar 31 04:10 /emul/linux/etc/mtab -> ../../../emul/linux/proc/mounts
 njoly@cixy [~]> /emul/linux/bin/df 
 /emul/linux/bin/df: cannot read table of mounted file systems: No such file or directory
 njoly@cixy [~]> sudo mount_procfs -o linux procfs /emul/linux/proc 
 mount_procfs: "/emul/linux/proc" is a relative path.
 mount_procfs: using "/usr/pkg/emul/linux/proc" instead.
