SubjectRe: [PATCH] modules_install

NO! This creates a race condition allowing malicious user to overwrite any
file if (s)he creates dozens of symlinks in /tmp. Using just pid to
guarantee uniqueness of the name is not enough. And we don't want do depend
on 'mktemp'... So I can't offer any good solution. A private directory in
/tmp? In a shell script and without race conditions - how?
