ファイルサーバーとして使うだけなら、わざわざ改造する必要はなかったのですが、そうではなかったとしても、ファイルサーバーの機能は入れておいた方が何かと便利です。
このサーバーに映像データをどんどん流し込むような使い方は、怖くてできませんが、ちょっとしたファイルの保管場所には適していると思います。
samba のインストールも数多く行ってきましたので、特にトラブルもなく動作しました。
最初の頃は、設定ファイルの書き方が、全く分かりませんでしたので、色々と悩んだものです。

#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.
