i need some answers...
1) I need to run some linux commands (from inside my app) that require
superuser privileges (mkfs, losetup, etc), how do i do that? (I do not
want to run my app with root privileges, but it will just ask the user
for the root password before proceeding)
2) When i execute the command i need to read its output (especially the
error messages) to know if everything went fine but i do not know how :(
3) How can i know if the user that is running my app is root or normal user?
