ash: allow execution of busybox-w32 binary without extension

2026-02-25T09:33:36+00:00

If the busybox-w32 binary didn't have an extension the shell was unable to spawn itself: $ ls -l busybox -rwxrwxr-x 1 rmy rmy 661006 Feb 25 09:37 busybox $ ./busybox sh $ ls sh: unable to spawn shell This happened because the shell used spawnve() from the C runtime to execute itself. Microsoft insists on trying to add an extension to the name of the binary unless it has an explicit '.' as its last character. Use the internal spawnveq() instead, as it handles various quirks like the above. Adds 16-32 bytes. (GitHub issue #566)
