script: Check ppm symlink, not its target Use `test -L` rather than `test -f` for `post-install.sh`. (Note: `[ ]` is an alternate invocation of the `test` shell builtin.) `[ -f some_path ]`, for a symlink "dereferences" the symlink, meaning it checks if its target (or the ultimate target, in the case of a chain of symlinks) exists and is a real file. By coincidence, as this runs after we extract/install ppm from the deb or rpm, the symlink target exists and is a real file. However, if we changed the install path for our package manager, the target might not exist, and this step might fail. `[ -L some_path ]` instead checks for if the path exists and is a symlink. This is more correct -- it's more directly what we're trying to check. So we will use `-L` rather than `-f`. 2023-01-07 06:41:42 +03:00			`if [ -L "$SYMLINK_PATH" ]`
