swap can be anywhere on the disks
swap is supposedly never used ...
why would you put swap in between ( / ) files you need hundreds of times
per hour and /var files and /usr files ...
the head has to skip over swap space
-- too much moving of the heads ...
- ask 100 people the same questions .. you will get 100 different replies
for where to put swap and why ... ( experimental data vs "i heard in
the grapevine" )

zero or all of the disk for "user"
the system should be able to clean itself
- log rotates in pariticular

100MB/day --> and you want 5GB ---> that last you about days
assuming there is no log rotation and compression
/var/log is temporary data
/var/cache or /var/apt is temporary or not .. depending on what you do
with the files

nah ...

i always use /opt ... and its "all the disks space" that the system doesnt
use

you should NEVER have to recover data in the first place ..
- something else is wrong if you do
- if you like fiddling with inodes and meta-data, that'd be fun

"better" is all relative to what and where's the imperical data or source
code is what is say
"power failure problems" is pretty much the same problems for all fs
- its a matter of how fast can you write your metadata
without corrupting the rest of the fs that was good prior to
the power failing and you have say 2ms to fix it all up and clean
up and exit before the disk write head goes bonkers
- writing during a power failure is crazy, even if its to flush
the cache
