UFS2 on i386 and amd64

[Manuel Stuehn]

Hi
I'm running momentarily FreeBSD 5.3BETA6-i386 and 5.3RELEASE-amd64 on my
  AMD64 3200+. Each installation has it's own primary partition where it
resides.
Is it possible to share /usr/ports, /usr/src/ and /usr/home/ on this
machine? In that way, that freebsd-amd64 and freebsd-i386 is working on
the same ports- and src-tree?
Or could this modus operandi cause data corruption?


regards
Manuel
