This fix is wrong. you deleted the target cache before executing
the new shell, thus defeating part of the purpose of ksu (to set
up a new security context, see the man page):
}else{
sweep_up(use_source_cache, cc_target);
execv(params[0], params);
com_err(prog_name, errno, "while trying to execv %s",
params[0]);
exit (1);
}
Also if you delete the fork then the target cache will remain after
you exit the new shell.
