-/* PSz 12 Nov 03
- *
- * Be proud that perl(1) may proclaim:
- * Setuid Perl scripts are safer than C programs ...
- * Do not abandon (deprecate) suidperl. Do not advocate C wrappers.
- *
- * The flow was: perl starts, notices script is suid, execs suidperl with same
- * arguments; suidperl opens script, checks many things, sets itself with
- * right UID, execs perl with similar arguments but with script pre-opened on
- * /dev/fd/xxx; perl checks script is as should be and does work. This was
- * insecure: see perlsec(1) for many problems with this approach.
- *
- * The "correct" flow should be: perl starts, opens script and notices it is
- * suid, checks many things, execs suidperl with similar arguments but with
- * script on /dev/fd/xxx; suidperl checks script and /dev/fd/xxx object are
- * same, checks arguments match #! line, sets itself with right UID, execs
- * perl with same arguments; perl checks many things and does work.
- *
- * (Opening the script in perl instead of suidperl, we "lose" scripts that
- * are readable to the target UID but not to the invoker. Where did
- * unreadable scripts work anyway?)
- *
- * For now, suidperl and perl are pretty much the same large and cumbersome
- * program, so suidperl can check its argument list (see comments elsewhere).
