Thanks cbkihong, I saw that already, this would probably require fork(); but it won't work for me, at least in the way I wanted, I have arbitrary number of processes started via system command, and I can't use their PIDs, plus the execution of the subroutine call itself is successful, so I cannot do even :
Code:
wait &sub-call;
    if ($? == 0) {
        # do something else;
}

I think I'll wait for STDIN interaction while "chomp"-ing the input, this should ensure that processes / SSH transfers in the background are done, assuming someone is looking at the external log file in real time.

NAME
dh_perl - calculates Perl dependencies and cleans up after MakeMaker SYNOPSIS
dh_perl [debhelperoptions] [-d] [librarydirs...] DESCRIPTION
dh_perl is a debhelper program that is responsible for generating the ${perl:Depends} substitutions and adding them to substvars files. The program will look at Perl scripts and modules in your package, and will use this information to generate a dependency on perl or perlapi. The dependency will be substituted into your package's control file wherever you place the token ${perl:Depends}. dh_perl also cleans up empty directories that MakeMaker can generate when installing Perl modules. OPTIONS
-d In some specific cases you may want to depend on perl-base rather than the full perl package. If so, you can pass the -d option to make dh_perl generate a dependency on the correct base package. This is only necessary for some packages that are included in the base system. Note that this flag may cause no dependency on perl-base to be generated at all. perl-base is Essential, so its dependency can be left out, unless a versioned dependency is needed. -V By default, scripts and architecture independent modules don't depend on any specific version of perl. The -V option causes the current version of the perl (or perl-base with -d) package to be specified. library dirs If your package installs Perl modules in non-standard directories, you can make dh_perl check those directories by passing their names on the command line. It will only check the vendorlib and vendorarch directories by default. CONFORMS TO
