Description
ISH 1.2.4 Build 447, IOS 15.7.3, iPhone 6s
when trying to use the login command to log in as another user one gets a "bad syscall" error.
After looking into dmesg it seems to be the syscall 216 which seems to be this syscall:
216 i386 setfsgid32 sys_setfsgid __ia32_sys_setfsgid

Research direction
Reproduce the failure by using the login command to switch users on the stated iOS and iSH versions, then inspect the dmesg output for syscall 216, identified as setfsgid32. Trace how that syscall is handled and verify that login as another user no longer reports a bad system call.
