#
# Reinstalling all installed binary packages, i.e. all packages which have an installation candidate.
# It is possible to pass a perl regular expression to narrow the search for installed binary packages which need to be 
# reinstalled.
# No manual user's consent will be asked before each package reinstallation.
#
########################################################################################################################
#
# Requirements:
# ------------
#
#  - We assume that apt alongside all its dependencies is already installed.
#
########################################################################################################################
#
# Parameters:
# ----------
#
# - <etc_enabled>: 
#       * true|yes: the binary packages will be reinstalled only if they contain at least one configuration file (in /etc)
#                   For advices about how to set related dpkg options in /etc/apt/apt.conf.d/local (for instance) to 
#                   control how the conffiles will be automatically managed during the reinstallation (without manual 
#                   user's consent'): 
#                       + --force-confold
#                       + --force-confnew
#                       + --force-confdef
#                       + --force-confmiss
#                   Cf. https://raphaelhertzog.com/2010/09/21/debian-conffile-configuration-file-managed-by-dpkg/
#                   The following message generated by apt is of interest:
#                   "Package distributor has shipped an updated version" 
#       * false|no: the binary packages won't be reinstalled if they contain at least one configuration file (in /etc)
#       * neutral:  the binary packages will be reinstalled whether or not they contain at least one configuration file (in /etc)    
#                   (default)
# - <perl_regex_include_pattern>: optional perl regular expression used with 'grep -P --' to narrow the search for the  
#                                 matched installed binary packages. Some special characters may need to be escaped.
#                                 Use with caution: setting <auto> to false is strongly advised when using 
#                                 <perl_regex_include_pattern>.
# - <perl_regex_exclude_pattern>: optional perl regular expression used with 'grep -Pv --' to exclude some binary packages
#                                 from the search. Some special characters may need to be escaped.
#                                 Use with caution: setting <auto> to false is strongly advised when using 
#                                 <perl_regex_exclude_pattern>.
