This is a simple security enhancing feature request.

Right now, OpenSSH on Fedora is compiled with "rlimit" as "Privsep sandbox style". Since OpenSSH 6.0, a newer sandbox style is available - "seccomp_filter".

I recommend that "--with-sandbox" compile option is changed to "seccomp_filter" to increase security of OpenSSH server.

OpenSSH in Ubuntu 13.10 is compiled with "seccomp_filter" sandbox.

Last time I tried, I was not able to login, it was probably related to GSSAPI authentication which is enabled by default in Fedora, see 

I'll prepare another build and try it again using upstream's fix.
