 I just notice that in my chrooted sandbox:
 # ls -l /proc/curproc/exe
 lr-xr-xr-x  1 root  wheel  1 Feb 21 07:14 /proc/curproc/exe -> /
 # file /proc/curproc/exe
 /proc/curproc/exe: symbolic link to /
 # file /proc/curproc/exe/
 /proc/curproc/exe/: directory
 
 and out of my chrooted sandbox:
 # ls -l /mnt/ccd0/sandbox/rust/proc/curproc/exe
 lr-xr-xr-x  1 root  wheel  7 Feb 21 08:14 
 /mnt/ccd0/sandbox/rust/proc/curproc/exe -> /bin/ls
 
 So yes, /proc/curproc/exe is not a regular file into a chrooted 
 environment. But I don't know if it is a problem from rust or from 
 NetBSD...
