unorderly shutdowns will, even will full journaling, lead to dataloss of all
data in the buffercache. Filesystem consistency is far more important,
having to resore any filesystem from tape is a pita. Especially ext2 was
very sensitive to unorderly shutdowns.

AIX LVM system (even booting from a LV, though not in the most elegant
fashion thinkable) is quite mature. It is one of AIX typical features I like
the most (unlike smitty... ;-)
