Hi, agama! Don't forsake me this time! I know I need to learn C, but what you said to me is like speaking in greek! I'm wrestling with a broken binary which is called by initramfs, I tried doing a gpkg-divert on the binary and calling it from a shell script. Something like:

Code:
#!/bin/sh

file=/tmp/filename
if [ -f $file ]; then
    rm -f $file
    exit 0
else
    $0.debian $@ # the name of the diverted binary
fi

Now, the binary is called in the beginning of boot, and it tells: /sbin/binary.debian: not found (while the binary is there...) The script works flawlessly, but fails when called by initramfs.

So I found that I should include this piece of code in the C source, but I don't understand a single piece of code in C and I'm in a big hurry.

I even feel like developing some tools in C (which is IMO the best language - powerful and lightweight), but it's too much for me in such a hurry.

Thanks!

NAME
fdutilsconfig - configure the suid bit of fdmount SYNOPSIS
fdutilsconfig DESCRIPTION
The fdutilsconfig script provides an interactive way to configure the suid bit of the fdmount(1) binary. It asks you some questions, give you a hint if needed, and enters your choice to /etc/fdmount.conf file. When upgrading the Debian fdutils package, the suid bit information stored in /etc/fdmount.conf is used to tell the new fdmount binary to keep your old suid bit settings. The script makes use of the suidmanager Debian package, if it is installed. If the script cannot find it, it manipulates the suid bit directly via `chmod u+s' command. FILES
fdutilsconfig reads and writes the configuration from /etc/fdmount.conf. This file is usually created when the fdutils package is installed for the first time. Please don't edit /etc/fdmount.conf manually! Use fdutilsconfig instead. NOTE
This script was written exclusively for the Debian GNU/Linux distribution. It is not a part of the upstream fdutils sources. AUTHORS
fdutilsconfig was adapted by Anthony Fok <foka@debian.org> from the gnuplotconfig script written by Tibor Simko <simko@debian.org>. SEE ALSO
