yeah i'm aware of most of these good points you raise, however would not
know how to implement my first syscall, i've been saving/bookmarking
resources which i believe could be helpful. i would definately need a
mentor on this project. it would be great also to see freebsd/zrouter on
300% more mips devices as most only have 4MB flash and this is one thing we
really need to get the filesizes down (don't forget bionic (derived from bsd
libc for android) bionics libc is very small, smaller infact than musl,
however i'm not sure how complete, and i believe much of the same work is
required as android uses the linux kernel.

yeah it builds fine as it has no dependencies.
currently it only has syscalls for linux (emulation) and any binary app
you
build against it has to be brandelf'd Linux.
I would like to see the freebsd syscalls, mutex/futexes coded into it so
it
could be a drop in replacement for the bsd toolchain when cross-compiling
for mips / zrouter.org.
plus i believe the mips kernel doesn't have linux emulation. (i could be
wrong). but yeah, a native port would require kernel hacking skills.
Only x86 has Linux compat support (amd64. i386, and pc98), and
true amd64 (64-bit, biarch) Linux compat is missing, FYI. It's a
doable task, but there would need to be some fudging done with the
syscall table (I committed a script in LTP which groks unistd.h for
this info on Linux), you'd need to add architecture dependent
syscalls, and do some other fun tasks.
Cheers,
