Re: Why /lib64 instead of /lib/x86_64?

The subject says it all.  /lib64 doesn't feel right.  Why add another root

Ditto for /usr/lib64. /usr/lib/x86_64 looks better to me.

IIRC, /usr/lib64 and /lib64 are "standard" for 64 bit systems .. not just the x86_64. So on a Sparc, Itanium or the IBM z/Architecture, you have 64 bit libraries in /usr/lib64 also.

Note that for Intel, we may well end up two sets of 64 bits libraries if
the rumoured Intel 64 bit extensions to IA32 are not compatible with the
AMD x86_64 ones.

Yes, but they're not both (amd & intel 64bit) going to be installed on a system at one time. You'l most likely see 32bit & 64bit mix, being i586 + amd64 or i586 + intel64.
