Not commenting on the exact behavior of Perl, but I have a coding style suggestion.

Perl's feature of returning the last evaluated value can be handy when you're writing quick code (or perhaps when you're golfing). But the code you wrote above is not very clear. Hand that to other programmers and I bet many won't know the return value - even plenty of Perl veterans.

Just because you can do something doesn't mean you should. Write more explicit code. For everyone's sake (including yourself a week/month/year in the future).

    [tye]: I don't know if you can just dismount, but I thought so.
    [davido]: yeah, umount -f isn't powerful enough.
    [tye]: probably something in the init subsystem that does the mounting that you could disable and reboot.
    davido needs to close laptop to board flight home from yapc.
    [davido]: I'll look into it in a few hours probably.
    [davido]: when i do get to that point I think I'll do it in a vm snapshot just in case. :)
    [oiskuu]: tye, you were right: loginuid/sessionid are part of task struct if compiled with AUDITSYSCALL. I have some doubts if you should actually depend on that feature.
    [Corion]: oiskuu: Depends on what you want to do with that information
    [tye]: I'm not depending on that feature. But I could in this environment. I'm using getlogin(). shrug
    [Corion]: For benign logging (which user started this DB instance), it's OK
