It is not untenable. All you have to do is make the script take input and save the selections somewhere.

If the chosen destination is /opt/yoursoftware/version

you can easily create an /opt/yoursoftware/latest that is a link to the version installed.

Windows does not have the major advantage here. Sure you can play games with the registry, but *nix has been more flexible for decades. Nobody is suggesting you build an alternative to deb or rpm files, but you don't have to use them at all, and it makes it even simpler for dealing with any ELF compatible UNIX.

you have a tgz file, and then it explodes into a directory. That then has an install.sh and perhaps an uninstall.sh and perhaps an upgrade.sh script inside.
They do the right thing, and create backups, and the version management and voila.

If you run uninstall.sh, it then asks if you want to save your current version. If so, you can easily archive it off, because /opt/yoursoftware/latest points to the one they just installed.

This is the way *nix works.

NAME
gimptool-2.0 - script to perform various GIMPy functions SYNOPSIS
gimptool-2.0 [--prefix[=DIR]] [--exec-prefix[=DIR]] [--version] [--help] [--quiet] [--silent] [-n] [--just-print] [--dry-run] [--recon] [--msvc-syntax] [--bindir] [--sbindir] [--libexecdir] [--datadir] [--sysconfdir] [--sharedstatedir] [--localstatedir] [--libdir] [--infodir] [--mandir] [--includedir] [--gimpplugindir] [--gimpdatadir] [--libs] [--libs-noui] [--cflags] [--cflags-noi] [--build plug-in.c] [--build-strip plug-in.c] [--install plug-in.c] [--install-strip plug-in.c] [--install-admin plug-in.c] [--install-bin plug-in] [--install-admin-strip plug-in.c] [--install-bin-strip plug-in] [--install-admin-bin plug-in] [--install-script script.scm] [--install-admin-script script.scm] [--uninstall-bin plug-in] [--uninstall-admin-bin plug-in] [--uninstall-script script.scm] [--unin- stall-admin-script script.scm] DESCRIPTION
gimptool-2.0 is a tool that can, among other things, build plug-ins or scripts and install them if they are distributed in one source file. gimptool-2.0 can also be used by programs that need to know what libraries and include-paths GIMP was compiled with. gimptool-2.0 uses pkg- config for this task. For use in Makefiles, it is recommended that you use pkg-config directly instead of calling gimptool-2.0. OPTIONS
gimptool-2.0 accepts the following options: --version Print the currently installed version of GIMP on the standard output. --help Print out the help blurb, showing commonly used commandline options. --quiet Run quietly without echoing any of the build commands. --silent Run silently without echoing any of the build commands. Same as --quiet. -n Test mode. Print the commands but don't actually execute them. Useful for making dry runs for testing. --just-print Test mode. Print the commands but don't actually execute them. Same as -n. --dry-run Test mode. Print the commands but don't actually execute them. Same as -n. --recon Test mode. Print the commands but don't actually execute them. Same as -n. --msvc-syntax Useful on Windows. Outputs the compiler and linker flags in the syntax used by Microsoft's toolchain. Passed to the pkg-config com- mand that does most of gimptool-2.0's work. --bindir Outputs the bindir used to install the GIMP. --sbindir Outputs the sbindir used to install the GIMP. --libexecdir Outputs the libexecdir used to install the GIMP. --datadir Outputs the datadir used to install the GIMP. --sysconfdir Outputs the sysconfdir used to install the GIMP. --sharedstatedir Outputs the sharedstatedir used to install the GIMP. --localstatedir Outputs the localstatedir used to install the GIMP. --libdir Outputs the libdir used to install the GIMP. --infodir Outputs the infodir used to install the GIMP. --mandir Outputs the mandir used to install the GIMP. --includedir Outputs the includedir used to install the GIMP. --gimpdatadir Outputs the actual directory where the GIMP data files were installed. --gimpplugindir Outputs the actual directory where the GIMP plug-ins were installed. --build plug-in.c Compile and link plug-in.c into a GIMP plug-in. --build-strip plug-in.c Compile,link, and strip plug-in.c into a GIMP plug-in. --install plug-in.c Compile, link, and install plug-in.c into the user's personal GIMP plug-in directory ($HOME/.gimp-2.8/plug-ins) --install-strip plug-in.c Compile, link,strip, and install plug-in.c into the user's personal GIMP plug-in directory ($HOME/.gimp-2.8/plug-ins) --install-admin plug-in.c Compile, link, and install plug-in.c into the system-wide GIMP plug-in directory (/usr/lib64/gimp/2.0/plug-ins) --install-bin plug-in Install plug-in into the user's personal GIMP plug-in directory ($HOME/.gimp-2.8/plug-ins) --install-admin-bin plug-in Install plug-in into the system-wide GIMP plug-in directory (/usr/lib64/gimp/2.0/plug-ins) --install-bin-strip plug-in Install stripped plug-in into the user's personal GIMP plug-in directory ($HOME/.gimp-2.8/plug-ins) --install-admin-bin-strip plug-in Install stripped plug-in into the system-wide GIMP plug-in directory (/usr/lib64/gimp/2.0/plug-ins) --install-script script.scm Install script.scm into the user's personal GIMP script directory ($HOME/.gimp-2.8/scripts) --install-admin-script script.scm Install script.scm into the system-wide GIMP script directory (/usr/share/gimp/2.0/scripts) --uninstall-bin plug-in Uninstall plug-in from the user's personal GIMP plug-in directory ($HOME/.gimp-2.8/plug-ins) --uninstall-admin-bin plug-in Uninstall plug-in from the system-wide GIMP plug-in directory (/usr/lib64/gimp/2.0/plug-ins) --uninstall-script script.scm Uninstall script.scm from the user's personal GIMP script directory ($HOME/.gimp-2.8/scripts) --uninstall-admin-script script.scm Uninstall script.scm from the system-wide GIMP script directory (/usr/share/gimp/2.0/scripts) --libs Print the linker flags that are necessary to link a GIMP plug-in. --libs-noui Print the linker flags that are necessary to link a GIMP plug-in, for plug-ins that do not require the GTK+ libraries. --cflags Print the compiler flags that are necessary to compile a GIMP plug-in. --clags-noui Print the compiler flags that are necessary to compile a GIMP plug-in for plug-ins that do not require the GTK+ libraries. --prefix=PREFIX If specified, use PREFIX instead of the installation prefix that GIMP was built with when computing the output for the --cflags and --libs options.
