I don't know exactly without looking at the code, but the results of

strace -e open sfdisk -d -g

look pretty complete to me.


By the way, the man page for sfdisk makes no mention of its ability to
scan all disk devices if none are specified on the command line and it
even seems to indicate that a device name is mandatory.

SFDISK(8) Linux Programmer's Manual SFDISK(8)

NAME
       sfdisk - Partition table manipulator for Linux

SYNOPSIS
       sfdisk [options] device
       sfdisk -s [partition]

Perhaps it would be better not to use this undocumented feature?
