What makes you think it does? OSv implements a subset of the Linux system call ABI and has a built-in ELF loader and linker. This allows OSv to run *unmodified* Linux binaries. Of course, if your application uses parts of the Linux ABI that are not supported, such as fork, they will not run very long. But OSv is capable of running unmodified Linux binaries for applications that restrict themselves to the subset of the ABI that OSv supports. - Pekka -- You received this message because you are subscribed to the Google Groups "OSv Development" group.
