With stow you can build the program to expect either the "real" path, or the "stowed" path, depending on your purposes.

      Let's take, for example, csh, which uses /etc/csh.cshrc and /dev/log and /bin/sh and many other files. The reason that all those filenames are listed in /etc/csh.conf is so that they can be changed.

      Now, some people want to move /etc/csh.conf itself. That's why csh looks for the /etc/csh.conf filename in a hashed /etc/registry.db file.

      Of course, on some machines, we need to move /etc/registry.db. That's why the registry filename is listed in a COMPILEDFREGISTRY environment variable.

      There's still the possibility of conflict with previous uses of the COMPILEDFREGISTRY variable. That's why the name of that variable is listed in /etc/fregistry_variable_name.txt.

      You say you want to move /etc/fregistry_variable_name.txt? You fool! We have billions of programs that /etc/fregistry_variable_name.txt at the top of main(). Everything _else_ has to be configurable, obviously, but /etc/fregistry_variable_name.txt isn't going anywhere.

      I don't understand why many people seem to assume 'tar good, rpm/dpkg bad'. For example, the article says:
      Although some Linux flavors such as Red Hat and Debian come with their own package management utilities (rpm and apt-get, respectively) that are as efficient as Stow, they work only on specific packaging formats (.rpm and .deb, respectively). When it comes to managing applications simply packaged in .tar files, Stow is the best bet.

      Why is a tar file any more 'simple' than an RPM or Debian package? If you are just storing a bunch of files, then yes. But what about metadata? That is, the information on dependencies (what libraries the package needs), where to get the source code, who the packager was, which version of the software these files represent, whether this packge conflicts with any other packages that might be installed, and all the other things that a decent package manager keeps track of automatically so you don't have to check them by hand, or get nasty surprises when you've installed a package and only later find a necessary library is the wrong version.

      If you use tar files then you'd need to have an extra metadata file inside storing this information: then you need to decide a format for that file and write a tool to parse it. And you've then reinvented rpm or dpkg, only with the spurious 'improvement' that people on other systems can unpack the archive if they have tar installed. As if anyone running a different system would need to unpack someone else's binary packages.

      Perhaps you could argue it would have been better for rpm to be based around tar.gz format, with the package details stored in the tarball as a script of some kind. But then it would become much slower to query a large directory of packages. Maybe that is important, maybe not. Also you have digital signatures to worry about, it's not clear how to do those with a tar archive (unless you have one tarball containing another tarball plus its PGP signature). Perhaps things could have been done differently, but the mere fact that the rpm and dpkg developers chose to make their own format rather than use tar is not an excuse for committing much more serious wheel-reinvention in making a kewl Yet Another packaging format.

      I'm not meaning to knock Gentoo here, that distribution really does do something new (building everything from source), and they perhaps had good reason to make a new packaging format. (Although it might have been worthwhile to investigate whether building from source could fit in with rpm or Debian source packages.) And Slackware has used tgz packages since the beginning, and doesn't seem that bothered about automatically tracking dependencies.

      But for most uses, I just don't see why 'simple packaging with tar' is particularly simple in the long run or much of an advantage.

      In windows, I double-click setup.exe, a GUI pops up, I pick the destination and off it goes. Why can't someone make something like this for Linux?

      A few reasons. Firstly, these programs are tremendously complex under the hood. Almost all generic ones (even light ones like NSIS) include their own scripting language. InstallShield 6 and up has used DCOM to provide remote procedure calls between the install script and the engine (ikernel.exe if you've ever wondered what that is). They do a lot of messing around under the hood in order to make things just work.

      Even then, they are too primitive for Linux. For instance, they have only basic concepts of dependancies. The lack of proper dependancy management almost brought Windows to its knees in the mid-nineties. Simply packaging every dependancy inside one self-extracting archive is simply not possible on Linux in any scalable fashion, so we have to build dependancy resolvers like apt. Windows installers tend to be GUI only. And so on.

      Now, systems like apt are pretty cool. When they work, they work really well. The problem is, that they tend to be built by distro projects, and then they are relatively tied to that distro. Apt as used on Debian for instance, is not the same as apt4rpm. URPMI is Mandrake, and emerge is basically tied to Gentoo, though I'm sure it could be generalised.

      So, the real solution is not to build Windows style setup.exe files. The real solution is to make something like apt, but that can be easily used by everybody, so you rarely if ever come across software that doesn't use it.

      There are two approaches to solving that problem. We're trying both at once. The first is to invent a new system, independant of the existing ones. See my sig. The second is to try and standardise key interfaces in a standards body, so that apt/urpmi/emerge and others can interoperate, and so you can plug distro-neutral packages into that framework. See here. Note - most of the activity so far related to that group has been off-list, hopefully there will be action starting in a few days.

    2. Stow has a serious bug in the way it handles directories. If only one package touches a certain directory, it simply creates a symlink to the directory. And then if another package puts something there, it then removes the symlink and does the normal thing. This is a good idea, however, Stow borks this up sometimes, which is bad.

    The reason is readily apparent. There is no clean, high-level way to specify installation details to make. Almost always "make install" invokes a messy ad hoc jumble of Bourne shell commands. Make has its own variables. Bourne shell has its variables. You end up double escaping all kinds of items and end up with $$Variables and a plethora of back ticks. The consequence is that install details in a make file tend to look like Perl's uglier cousin. Throw in line extension by escaping line ends with a reverse solidus, and you have the makings of a maintenance nightmare. Try previewing "make install" with "make -n". Not too helpful is it?

    How to fix it? I don't know. Perhaps if all Unix vendors could agree on an "installation specification language" -- ISL. Then each vendor's "make" program could incorporate an interperetter for ISL. Other programs like Linux RPM could benefit for this too and incorporate an ISL interpreter because RPM installation specifications are only slightly better than plain Bourne shell (although definitely a step in the right direction).

More recently packaging systems have gained widespread acceptance by people so tools like stow have not been as amazingly handy.

This is of particular utility when you have a network of machines and want the same applications available everywhere. Pick a machine and have it NFS share the applications. In these situations Stow still is important. Maybe the stock packaged Perl is not good enough, maybe you want the multithreaded options and a few extra modules from CPAN. Then creating a new Perl directory and stowing it somewhere else is handy.

    We (the Tcl core developers) have had problems in the past with Stow, mainly because it relies on being able to specify the installation process at 'make-install' time instead of normal 'make' time, leading to messed up baked-in paths... :^/

    Yes, but that's only a problem with the stow documentation. Use "--prefix=" during configure and you'll have no worries at all (except that the "baked-in" package names will be '/usr/local/stow/yourpackage/etc ...', but that has never mattered to me and I have about fifty stow packages installed on my system, with everything from gtk-2.2 to lyx to rxvt).

    I have used stow for the past year and absolutely love it. It allows me to have complete control over all the software I compile by had, as opposed to the base system installed by my distro. And since I have a bash alias to ./configure to include an automatic prefix assignment based on the directory name I'm configuring from (which is almost always based on the name and version number of the software), I can compile a new version and

    stow -D /usr/local/stow/foo-1.2

    stow /usr/local/stow/foo-1.3

    ... without losing my old version that I know works. (so, if my new version segfaults, I can "install" the old one simply by reversing the above process)

    And ... I can do a simple "du" command in the /usr/local/stow directory to see exactly how much disk-space each package is using and I can easily find, modify or delete a part of a package I compiled months ago!

    Stow is one of the most fantastic pieces of software, and it's simplicity itself as well. It reports conflicts and only installs sym-links. The scary thing is that this is the first and only time I have ever seen it reach "mainstream" coverage - like most of the best linux software, it seems to be unheard of and unused.
