Even filter-flags -fPIC didn't have anyy effect. CC="${CC} -yet_exec" did however work.

This actually should be pretty easy to fix to make it PIC aware.. Looks like it's just a standard _sysctl2() define.. #ifndef __ia64 /* breaks ia64. */ static _syscall2(long, create_module, const char *, name, size_t, size); #else #define create_module(name, size) \ syscall(__NR_create_module, (name), (size)) #endif
comment 1 works at least
Created attachment 25104 [details, diff] devfsd-1.3.25-pic.patch Remove backwords compat stuff that was ignorantly take from mode-init-tools. This allows us to build devsfd with PIC/PIE
Created attachment 25105 [details, diff] devfsd-1.3.25-r5.ebuild.diff
Note this should work for all arches.
pic patch seems to have done the trick too.
cool.. I'll -r6 this in about 3-4 cups of coffee from now
glibc is not playing along for me when I do a repoman --pretend scan thus blocking me from commiting at this time. I'm getting conflicts from ppc64. If I did merge it I would have fudge a little and I would rather not. I dont know if this a bug or feature so I'm going to try to get some input here.
