It is not SHF_ALLOC, so it will not make it into vmlinuz either.

? gcc-2.96-RH (2.96-91 and above) and recent gcc 3.1 CVS together with recent binutils support merging strings already. Unlike killing .comment/.note sections, this saves real kernel memory.
This reminds me, I should finally hack up binutils so that it uses SHF_MERGE for .ident directives automatically.
