System call tracing in Linuxulator

[Martin Cracauer]

Didn't we use top have a linux-strace port?

It seems that there is currently no stracing tool which would resolve
Linux system calls to some text description.


Using the strace Linux binary fails with an invalid argument to
ptrace:
./strace /compat/linux/bin/cat 
execve("/compat/linux/bin/cat", ["/compat/linux/bin/cat"], [/* 56 vars
*/]) = 0
trace: ptrace(PTRACE_SYSCALL, ...): Invalid argument

FreeBSD truss of the above strace ends with:
linux_ptrace(0x18,0x17c41,0x1,0x0)               ERR#22 'Invalid argument'
trace: ptrace(PTRACE_SYSCALL, ...): Invalid argument

What are people using these days?
