The pack prefix flag allows you to override the installers install path
You can do this by adding the --prefix flag to the end of a pack flash command. Like below
pack flash installer.pack --prefix $HOME/Amazing_Software
This will force the software to be installede at ~/Amazing_Software. But be warned
Some software WILL NOT WORK if installed somewhere else thats not its install path.
If you encounted a problem with software not working try installing it without
the prefix flag.
