I'm working on creating custom made LiveISO with catalyst and noticed that dev-vcs/git takes enormously large space after creating SquashFS image like this:
du -h */usr/libexec/git-core --max-depth=0
After some investigations I found that catalyst uses pyDeComp library that not preserves hardlinks (see https://github.com/dol-sen/pyDeComp/issues/10).
dev-vcs/git also supports build option INSTALL_SYMLINKS which replaces subcommands' hardlinks to git binary with symlinks. While this is rather catalyst issue, it would be great to introduce USE=make-symlinks to reduce image size for such cases.
