One issues I'm aware of is that FreeBSD emulates the Linux kernel only up to version 2.6.something whereas CentOS 7 is built on 3.10. Many programs which don't use the newer features still work fine, but some -- I'm not sure how many and important these are -- require the newer features. > All the supported FreeBSD versions can use c7 and there's no > reason to use c6. Another issue is that RHEL 7 actually doesn't support i386. CentOS 7's i386 packages are provided by their AltArch[1] SIG. I'm not sure how closely they follow the x86_64 updates, both in package coverage and release timing, and if this creates problems in practice. Having said that I'd prefer c7 to be the default as well, if/once possible. 1. https://wiki.centos.org/SpecialInterestGroup/AltArch/i386
