The stuff the distros ship is also not so nice in that you can't dump to LVM or SAN or ... etc; kexec gets all that right. It's also far more an all-or-nothing thing; if you make the transition you know you're going to get a good dump; most of the other dumps die halfway in the process at some point. --=-CnmM3x3ygs98qRMu8doP Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.1 (GNU/Linux) iD8DBQBCuIjJpv2rCoFn+CIRAjsKAJ9W/zOsiqzGc09x8P8GmNrM4mPzZQCfeFLp hjfDWmbbW1PVhDhYXlp4UTo= =Bi5A -----END PGP SIGNATURE----- --=-CnmM3x3ygs98qRMu8doP--
