NAME

       febootstrap-minimize - Minimize an febootstrap image

SYNOPSIS

        febootstrap-minimize [--options] DIR

DESCRIPTION

       febootstrap-minimize minimizes an febootstrap(8)-created filesystem.
       This means that unneeded files and cruft are removed from the image.

       If no options are given, the default is to minimize the image as much
       as possible.  This means, for example, that locales are removed so the
       image will only be usable in US-English, there will be no documentation
       or manual pages, and the image will only work in a UTC timezone.

       Note that image minimization involves deleting files that have been
       installed by RPM.  Thus after minimization, it is no longer guaranteed
       that RPM will function correctly on the image.  You should only do this
       as a final step for "throwaway" appliances that do not need to be
       modified or upgraded in future.

OPTIONS

       --all
           Perform all minimization operations, to produce the smallest
           possible image.  Note in particular that locales are discarded.

           You can perform all minimization operations except X, Y and Z by
           doing:

            febootstrap-minimize --all --keep-X --keep-Y --keep-Z ...

           ("--all" can be omitted since it is the default).

       --none
           Start with no minimization operations.  You can specify only
           minimization operations X, Y and Z like this:

            febootstrap-minimize --none --drop-X --drop-Y --drop-Z ...

       --keep-locales
       --drop-locales
           Keep or drop locale support.

       --keep-docs
       --drop-docs
           Keep or drop documentation, man pages and info files.

       --keep-cracklib
       --drop-cracklib
           Keep or drop cracklib libraries.

       --keep-i18n
       --drop-i18n
           Keep or drop "/usr/share/i18n".

       --keep-zoneinfo
       --drop-zoneinfo
           Keep or drop all timezones (except UTC which is never deleted).

       --keep-rpmdb
       --drop-rpmdb
           Keep or drop the RPM and YUM package databases.  Obviously RPM and
           YUM will be completely non-functional if you drop these.

       --keep-yum-cache
       --drop-yum-cache
           Keep or drop the yum cache.  Note that febootstrap(8) has already
           deleted this directory unless you ran it with the "--no-clean"
           option.

       --keep-services
       --drop-services
           Keep or drop the "/etc/services" file.  If dropped, this file is
           replaced with a very minimal one which just lists the most common
           services.  For less common services you will have to refer to them
           by port number instead of name.

       --keep-sln
       --drop-sln
           Keep or drop "/sbin/sln" (statically linked "ln").  This is not
           really required in minimal appliances.

       --keep-ldconfig
       --drop-ldconfig
           Keep or drop "/sbin/ldconfig", "/etc/ld.so.cache" and
           "/var/cache/ldconfig" (the dynamic linking cache).  This is not
           needed.  Dynamic linking during program execution will be
           marginally slower.

       --pack-executables
           This option has been removed in febootstrap 2.5.  In previous
           versions it was used to pack executables using the external "upx"
           program.  However it was not enabled by default and never worked
           very effectively.

TODO

       ·   Deduplicate files with the same content (by hardlinking them).  See
           the program hardlink(1).

       ·   Remove unused binaries.

       ·   Remove unused libraries.
