sys-block/silo fails to emerge with linux-headers-2.6.19.2-r1 because it doesn't install ufs header files which silo uses to support solaris booting.

Created attachment 107278 [details, diff] linux-export-ufs-fs-header.patch
Works like a charm with 2.6.20 headers, please apply.
as noted on irc, this is merely a workaround until silo is fixed so you want me to apply the workaround and leave the bug open until you fix silo ?
Never mind, a compatible header is shipped in silo itself, however it's never used, i've patched the ebuild to do so. Is ufs_fs.h supposed to be gone from standard headers? So as to report (or not) this upstream.
there's two parts to the patch ... first, exporting ufs_fs.h to userspace which i personally think is OK ... the second part, exporting the old large struct is not ok and requires updates to the silo code i can handle forwarding the ufs_fs.h bit to lkml
