I think so, yes. My /usr/local may vary by more than 50G (very quickly, but
very rarely), for example. When it's not eating up ~60-80G, I'd like this
space to be available for something else, probably /home.
So, it's either binding/linking the trees on a single filesystem (what I
would call a hack), using LVM more than I should, or stopping just a second
to think about the advantages of partitioning that I can afford to lose.
And the cpu overhead for using separate partitions and lvm - again with
Hmm, it works the other way around: you usually get performance boosts
*from* the separation of your volumes. Even if you simply want the best
performance, and you have the time and interest to actually look into it,
you might still find yourself wondering, like me, if it is necessary at all
to think about any volume layout.
(Since we're talking about the burden of thinking, I'd say going with a
single root filesystem is quite easier.)
Now, as we just discussed, it's not all about CPU and disk space, but
sometimes about practicalities (reinstallation, block level operations,
boot) or safety (mount options, filesystem corruption containment, free
my default laptop build is
partition 1 /boot - ext2 or ext3 about 500M - 1G
swap = to mem - my last 3 laptops have >3G memory so if I am swapping
there is something wrong
rest = 1 big partitions currently ext4
As it seems you're already alright with losing the benefits of partitioning
(except for your boot partition, which might not even be necessary in your
case), but most people still believe it's better to take the time to
separate the data into several filesystems (even just a few), for a workstation.
