>Description:
I have installed doas on a system running NetBSD 9.2. /usr/pkg/etc/doas.conf includes the line:

permit nopass dca as root cmd /sbin/reboot

If I do

doas /sbin/reboot

from a shell in my account, the system hangs and fails to reboot.

On the other hand, I also have sudo installed, with this line in the sudoers file:

dca     giovanni = NOPASSWD: /sbin/reboot

and I do

sudo /sbin/reboot

the system reboots properly.

I have used the identical doas.conf on openbsd and freebsd and 'doas /sbin/reboot' works properly.
