I know it's not the safest thing to do, but I have the key for the other 
volumes on the root volume, so that this is the only one for which I need a 
passphrase. And no I can't put them on a USB stick, because USB is 
(physically) defective on this Laptop :-(

Can't remember when e2fstools were dropped from Gentoo, but resize2fs is 
part of e2fsprogs.

The only contra I know is that EVMS currently (still) can't handle online 
ext2/3 resize, but you can still do it manually as you would with pure LVM 
anyway. (Or use a different fs).

Other than that it IMHO has only pros. Be it partitioning, sw raid, logical 
volumes, fs creation, resizing, even mounting :-) - everything is done in 
one single tool.

Not more than LVM. The terminology is a bit different though, but once 
you're used to it it is much simpler. I switched from LVM (1) to EVMS its 
early stages (kernel 2.4) and never looked back.

Bye...
