 =head1 NAME
 
 ksb::OSSupport
 
 =head1 DESCRIPTION
 
 Provides support code for handling distro-specific functionality, such as lists
 of package dependencies, command lines to update packages in the first place,
 and so on.
 
 See L<https://www.freedesktop.org/software/systemd/man/os-release.html> for the
 relevant specification.
 
 B<NOTE> This module is supposed to be loadable even under minimal Perl
 environments as fielded in "minimal Docker container" forms of popular distros.
 
 =head1 SYNOPSIS
 
     my $os = ksb::OSSupport->new; # Autodetects info on running system
     say "Current OS is: ", $os->vendorID;
 
 =cut
 
 =head1 METHODS
 
 =head2 new
 
     $os = ksb::OSSupport->new;
 
     # Manually point to os-release
     $os = ksb::OSSupport->new('/usr/lib/os-release');
 
 Creates a new object. Required for other methods.

 sub new
 {
     my ($class, $file) = @_;
 
     my $self = bless {
     }, $class;
 
     # $file might be undef
     my @kvListRef = $self->_readOSRelease($file);
 
     # Result comes in a listref which itself contains 2-elem
     # lists... flatten list so it can be assigned to the hash
     %{$self} = map { @{$_}[0,1] } @kvListRef;
 
     return $self;
 }
 
 =head2 vendorID
 
     my $vendor = $os->vendorID; # 'gentoo', 'debian', etc.
 
 Returns the vendor ID from the I<os-release> specification.
 
 =cut
 
 sub vendorID
 {
     my $self = shift;
     return $self->{ID} // 'unknown';
 }
 
 =head2 vendorVersion
 
     my $vendor = $os->vendorVersion; # 'xenial', '17', etc.
 
 Returns the vendor Version from the I<os-release> specification.
 The first available value from C<VERSION_ID> and then
 C<VERSION_CODENAME> is used, and 'unknown' is returned if neither
 are set.
 
 =cut
 
 sub vendorVersion
 {
     my $self = shift;
     return $self->{VERSION_ID} // $self->{VERSION_CODENAME} // 'unknown';
 }
 
 =head2 bestDistroMatch
 
     # Might return 'fedora' if running on Scientific Linux
     my $distro = $os->bestDistroMatch(qw/ubuntu fedora arch debian/);
 
 This uses the ID (and if needed, ID_LIKE) parameter in
 /etc/os-release to find the best possible match amongst the
 provided distro IDs. The list of distros should be ordered with
 most specific distro first.
 
 If no match is found, returns 'linux' (B<not> undef, '', or
 similar)

         push @ids, split(' ', $likeDistros);
     }
 
     foreach my $id (@ids) {
         return $id if first { $id eq $_ } @distros;
     }
 
     return 'linux';
