Depends what the machine is doing. Aside from wanting to split / and /home into different filesystems I can't really see any reason to have anything but /, /boot, and swap. Especially for a desktop. BTRFS quotas should keep the various subvolumes under control space-wise, if you have that concern.
I wouldn't want to rely on BTRFS quotas at this time. It's a feature that hasn't had a lot of testing.
I've noticed that Debian, in the "do everything for me" installation mode seems to put / before swap, which means if it's a VM and you later want to expand the disk, you'd need to shuffle things around a bit. For a VM though, I'd be running btrfs on the hypervisor and then run the VM on NFS, leaving the hypervisor to take the snapshots etc (depending on the VM workload - maybe NFS isn't so good for databases... I haven't checked recently).
NFS is generally poor for any task that requires good write performance. For some of my virtual servers I have MySQL and Dovecot running in the Dom0 so that the DomUs have less disk intensive tasks. On Sun, 24 May 2015 09:59:30 AM Wen Lin wrote:
How big is your computer's memory? I would have thought 20 GB for swap space is a bit too much. Usually = or double the memory size will do?
http://etbe.coker.com.au/2007/09/28/swap-space/ Double RAM has never been a particularly good measure for allocating swap, and now that RAM is often 4G or more it's especially unsuitable. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
