how to open elf file image from inside genode? libbacktrace question

[Alexander Tormasov]

Returning to my question, could I use posix open(«/test-go») to open my binary from which I run executable, if I have the following code in run file:

        <start name="test-go" caps="250">
            <resource name="RAM" quantum="20M"/>
            <config verbose="yes" ld_verbose="yes" >
                <vfs> <dir name="dev"> <log/> </dir> </vfs>
                <libc stdout="/dev/log" stderr="/dev/log"/>
            </config>
        </start>

or I need to modify it and add another «double» option, something like

        <start name="test-go" caps="250">
            <resource name="RAM" quantum="20M"/>
            <config verbose="yes" ld_verbose="yes" >
                <vfs> <dir name="dev"> <log/> </dir>
			<rom name="test-go"/>
		</vfs>
                                <libc stdout="/dev/log" stderr="/dev/log"/>
            </config>
        </start>
