   This is an exact replica of my reply in the sharun repo:

   Hi, sstrip is https://github.com/aunali1/super-strip.git, it is used in varios projects Gunzo maintains, the binary was UPXed and put into the CI directory because fetching it from a secondary repo would be slow.

   Here's the place where it is built: https://github.com/VHSgunzo/squashfs-tools-static/blob/a7aab8e141734b2eecf32d4c4d0aee74b533fd30/build.sh#L136C1-L149C3

   I shouldn't have wasted my time reverse engineering it with gdb and this .py script; https://github.com/akamai/akamai-security-research/blob/main/UPX/oepfinder.py

   Once I realized it was super-strip I just looked at Gunzo's repos looking for that and I found the place where the file is built

   Still quite strange it's not built from source as it seems quite small as is.

   the dwarfs repository will be removed in the next version of uruntime, i.e. size optimizations are now done in upstream
