While investigating a bug with the --emulate-fhs option (bug report forthco= ming) I noticed that the profile contents can depend on the order of packag= es given as input to guix shell. The FHS bug is also due to argument order,= but I think is clearly a bug and not expected behavior (wrong glibc includ= ed in the container). Though maybe we want to look around for other argumen= t order problems or have some tests? Actually, this is true for profiles more generally, as I just quickly teste= d the first example with "guix install" rather than just shell. My examples= are all with shell, but I guess it comes down to the same thing. I think t= his is trickier with shell and the -D option, as we'll see in the second ex= ample. First example, where we might expect something to happen, though personally= I expected a profile collision error: --8<---------------cut here---------------start------------->8--- =E2=9D=AF guix shell ffmpeg@4 ffmpeg@5 =E2=9D=AF ls -la $(which ffmpeg) lrwxrwxrwx 1 root root 67 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/bin/ffmpeg -> /gnu/store/51gal8hjxilk1f26f3m3ggdhg9rykz6s-f= fmpeg-5.1.2/bin/ffmpeg* =E2=9D=AF ls -la $GUIX_ENVIRONMENT/lib/libavdevice.so* lrwxrwxrwx 1 root root 75 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/lib/libavdevice.so -> /gnu/store/51gal8hjxilk1f26f3m3ggdhg9= rykz6s-ffmpeg-5.1.2/lib/libavdevice.so* lrwxrwxrwx 1 root root 78 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/lib/libavdevice.so.58 -> /gnu/store/hx4xf70yjgycx0asv1k1h33= p7xms15m8-ffmpeg-4.4.2/lib/libavdevice.so.58* lrwxrwxrwx 1 root root 85 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/lib/libavdevice.so.58.13.100 -> /gnu/store/hx4xf70yjgycx0as= v1k1h33p7xms15m8-ffmpeg-4.4.2/lib/libavdevice.so.58.13.100* lrwxrwxrwx 1 root root 78 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/lib/libavdevice.so.59 -> /gnu/store/51gal8hjxilk1f26f3m3ggd= hg9rykz6s-ffmpeg-5.1.2/lib/libavdevice.so.59* lrwxrwxrwx 1 root root 84 Dec 31 1969 /gnu/store/ivfa3mjhqiqc91m5h27sr9gfy= zwnv1d0-profile/lib/libavdevice.so.59.7.100 -> /gnu/store/51gal8hjxilk1f26f= 3m3ggdhg9rykz6s-ffmpeg-5.1.2/lib/libavdevice.so.59.7.100* --8<---------------cut here---------------end--------------->8--- Note that the last specified package, ffmpeg@5, takes precedence here for b= in, and the lib directory contains a mixture (as there are some unique file= names as well).

We might expect this can get rath= er confusing given a few inputs and different versions. Is this the expected behavior? In discussing with nckxhexen on #guix, it se= emed something that should be messaged to the user. Perhaps a warning that = there is a potential conflict/collision as one package is overriding or sha= dowing the other. And documented. The behavior itself seems predictable and= perhaps the best choice here, if it is communicated. Thoughts? Patches? Thanks! John
