is a great Unix implementation, to make your life easier when it comes
down to Unix software installation. We will give you a few reasons why
you should try it. All you need is a Unix system with Perl 5.6
of Packaging Systems?
is an invitation for you to stop worring about packages. Some packaging
systems are very good, some not. Some will leave directories all over your
drive, after uninstallation or upgrade. Some will have bad written scriptlets.
Some will be *VERY* incompatible or uninstallable under its own
distribution version cycle.
you can even use a RPM to install on! Relocation the package to /app/name-1.0
-ivh package.rpm --relocate\ /usr=/com/app/package-1.0 --bareloc
even decompress a tarball compiled!
-zxvf tarball.compiled.tar.gz -C /app/compiled-name
doubt, the tarball sources are the ones always prone to work in every *nix
system. You compile your own applications, optimized for your machine instructions
and performance, and fitting your current *nix configuration.
there is a price... Uninstallation can drive an 'obssessed clean' user
go mad. The "make install" command fills your /usr/local
whatever the prefix you chose) throughout the several subdirectories, mixing
all programs data into a single entire directory.
times , "make uninstall" will not remove 100% of the crap you installed.
And for that, you need to keep your sources compiled in the drive, wasting
precious disk space.
is where relink comes in. If you are thinking compiling is fun and a didactic
process, it will be even more with Relink.
will create a separate directory for each application, and make them fully
usable and deletable, providing the most clean machine, in terms of organization.
will link or relink all files from its application directory to a global
virtual application directory.
how it's easy: For example...
application is now in /app/crap-1.0.3
will be activated from /vapp
you noticed, a symbolic link to /a/app
your programs are stored)
----- (where your programs are ran from -
actual dir of your program)
your life easier)
your life easier)
dir (Virtual Application) is the directory that will provide the links
distributed in their respective directories, bin, etc, lib, share, include...
is the funniest part. It was never simples as this. SIMPLY DELETE
your application dir, and RELINK.
remove the crap, installed above.
it's DONE! Not a single trace of the program onto the drive! Now, how would
you know if "make uninstall" would do it?
If I screw up my /vapp
or the database?
you can do that at any time! :-)
is never work, unless you're on a RPM based system or other package management!
you screw the whole thing, deleted files from /vapp, you can anytime do:
is right back there! Still running! The database was WIPED and RECONSTRUCTED
