This one is identical to previous patch except it states v2 to clearly
indicate it is 2nd version of the original patch I sent in December. It is
essentially a minimal subset of ROFS implementation without cache layer. It
also does not include unit tests.
I will be sending a followup patch to
The Read-Only File System (ROFS) is a simple implementation of
a file system where data from disk can only be read from and never
written to. It is simple enough for many stateless applications
deployed on OSv which only need to read code from local disk and never
write to local disk. The ROFS is
I am trying to implement the idea that Nadav proposed to save memory when

I saw the exodus announcement too - very nice. I wondered if you could
alter it to emit a C program that dlopen()s the binary, looks up
Good news -- some of the code I was hoping to build just came out, and
since I didn't write it, it's actually pretty good :D

or:
pip install exodus-bundler
Run:
exodus ssh -t | tar xz
And you get a self contained binary distributon, for most things short of
So Exodus will in fact compile an executable, via dietlibc or musl, but
it's an execve wrapper, and it seems you've stubbed that.
You have to change the relevant line in src/exodus_bundlers/launchers.py to:
args = initial_args + ['-shared', '-fPIC', '-O3', input_filename,
'-o',
