pivot_root in perl ?

abachus has asked for the wisdom of the Perl Monks concerning the following question:

Hello all,

I'd like to perform a pivot_root(2) on a remote machine,
but i don't really want to sit here and write the program
in C. Is there such a perl function or module that could
handle the task at hand.

many thanks

Nothing jumps out on CPAN, but it should be trivial to use either syscall or Inline::C to call it.	[reply]

You can just run the pivot_root command, assuming it's available, ofcoure. "What should it profit a man, if he should win a flame war, yet lose his cool?"	[reply]

Also, as you probably have to run pivot_root only very rarely, you can write only that part as a separate C program and call that from perl. Update: I seem to have it as a pre-installed program on my debian system too.	[reply]
