By the way, on powerpc*, we have a little hack in place to be able to load symbols even when loader isn't in use -- in petitboot, if you provide a second copy of the kernel as the initrd, it will be used at runtime to load symbols. (the powerpc code has special probing to skip attaching the initrd as a md device if it looks like an ELF file) And on powerpc32, you can actually netboot loader instead of netbooting the kernel (with a little dhcpd magic) and get symbols loaded the "normal" way. -- Brandon Bergren bdra...@freebsd.org _______________________________________________ svn-src-head@freebsd.org mailing list https://lists.freebsd.org/mailman/listinfo/svn-src-head To unsubscribe, send any mail to "svn-src-head-unsubscr...@freebsd.org"
