=head1 NAME
Bugzilla::Install::Filesystem - Fix up the filesystem during
installation.
=head1 DESCRIPTION
This module is used primarily by L<checksetup.pl> to modify the
filesystem during installation, including creating the data/ directory.
=head1 SUBROUTINES
=over
=item C<update_filesystem({ index_html => 0 })>
Description: Creates all the directories and files that Bugzilla
needs to function but doesn't ship with. Also does
any updates to these files as necessary during an
upgrade.
Params: C<index_html> - Whether or not we should create
the F<index.html> file.
Returns: nothing
=item C<fix_all_file_permissions($output)>
Description: Sets all the file permissions on all of Bugzilla's files
to what they should be. Note that permissions are different
depending on whether or not C<$webservergroup> is set
in F<localconfig>.
Params: C<$output> - C<true> if you want this function to print
out information about what it's doing.
Returns: nothing
=item C<fix_dir_permissions>
Given the name of a directory, its permissions will be fixed according to
how they are supposed to be set in Bugzilla's current configuration.
If it fails to set the permissions, a warning will be printed to STDERR.
=item C<fix_file_permissions>
Given the name of a file, its permissions will be fixed according to
how they are supposed to be set in Bugzilla's current configuration.
If it fails to set the permissions, a warning will be printed to STDERR.
