### Bug Description When staging a debian package which includes a symlink to another location within that debian package, there is an attempt to fix that link: ``` 2024-02-27 18:45:37.303 fix artifacts: unpack_dir='/root/parts/my-part/install' 2024-02-27 18:45:37.304 fix symlink: path='/root/parts/my-part/install/lib/modules/6.5.0-9-generic/build', unpack_dir='/root/parts/my-part/install', root='/root/parts/my-part/install/lib/modules/6.5.0-9-generic' 2024-02-27 18:45:37.387 fix symlink: target='/root/parts/my-part/install/usr/src/linux-headers-6.5.0-9-generic' ``` However, this fix does not take into consideration that the name (location) of the link file may change when using `organize`. Likewise, the fix does not take into consideration that the name (location) of the target file may change when using `organize`. I chose the package I did simply because it was the easiest package I knew of with an important symlink. However, any debian package should work. The relevant code appears to (only?) run in the case where a `stage-package` is specified, and only on that package's contents. (I could not reproduce this behavior with a contrived `source: dir/` part). ### To Reproduce Install snapcraft from latest/stable (used revision 10595) and attempt to build the below `snapcraft.yaml`; I used `snapcraft build my-part --shell-after --verbosity=debug` to do some exploring. Note that I organize two different directories; removing either line in `organize` will result in similarly broken links. ### part yaml ```shell name: my-snap-name # you probably want to 'snapcraft register <name>' base: core22 # the base snap is the execution environment for this snap version: '0.1' # just for humans, typically '1.2+git' or '1.3.2' summary: Single-line elevator pitch for your amazing snap # 79 char long summary description: | This is my-snap's description.
