On sun4m machine, mkraid aborts with a kernel message
"Unimplemented SPARC system call 140". I tried compiling
raidtools-19990713-0.90.tar.gz and received the same error.
If I #define __usparc__ in raid_io.c, mkraid seems to work
ok but then very strange things happen on the system
identical to Bug ID 2807 (e.g. running vi gives cannot
execute binary file /bin/vi).
Fixed in the new raidtools avalable from rawhide.
