It is strange, cursory digging for an explanation was a little more complex than I bargained for... https://github.com/torvalds/linux/blob/v6.17/fs/binfmt_script.c#L121-L134 https://github.com/torvalds/linux/blob/v6.17/fs/binfmt_scrip... I think it makes it to calling open_exec but there's a test for BINPRM_FLAGS_PATH_INACCESSIBLE, which doesn't seem relevant since 'bash' isn't like '/dev/fd/<fd>/..', but does provoke an ENOENT. https://github.com/torvalds/linux/blob/v6.17/fs/exec.c#L1445 https://github.com/torvalds/linux/blob/v6.17/fs/exec.c#L1445 Maybe someone else can explain it, I'd enjoy the details, and ran out of steam.
