alpine(3.14+)bash都有问题

This is related to faccessat2 syscall has been enabled in musl in alpine starting 3.14. Due to a bug in runc it fails if your kernel do not support faccessat2.
Short answer update runc to >= 1.0.0-rc93 or update kernel to 5.8 (upgrading kernel should work but i haven't tested it)
