> There are several portability problems preventing from compiling native component on
freebsd.
> 1. libgen.h is not included. correct function prototype is there but linux glibc has
workaround to define it for user if libgen.h is not directly included. Include this file directly.
> 2. query max size of login name using sysconf. it follows same code style like rest of
code using sysconf too.
> 3. cgroups are linux only feature, make conditional compile and return error if mount_cgroup
is attempted on non linux OS
> 4. do not use posix function setpgrp() since it clashes with same function from BSD 4.2,
use equivalent function. After inspecting glibc sources its just shortcut to setpgid(0,0)
> These changes makes it compile on both linux and freebsd.
