Thanks! Lembas and Magic Banana,
I was reviewing the Debian doc and saw a big error in my thinking, I thought
it had suggested /usr be on a separate partition but it never does.
> ...one more partition whose use is to be estimated to avoid
under/over-dimensioning
but
"Any directory tree which a user has write permissions to, such as e.g.
/home, /tmp and /var/tmp/, should be on a separate partition. This reduces
the risk of a user DoS..."
It seems from the Audicity information that a /var/tmp partition required to
address the DOS and Symlink concerns would need to be generous. Yes, I might
like to make music someday. I suppose a 3d modeling program like Povray might
be similar. I imagine they have some information indicating how big a
/var/tmp partition would have to be.
I think I am arriving at some clarity, here's the new scheme but wll add
maybe a 3 GB /var/tmp (also ext2)
|.................*.***extended partition***.*......................|..swap
partition.|../home partition..|
../@16 GB../tmp@6 GB../var/log@1 GB../opt@3.2 GB |..swap@8 GB.....|../home
@532 GB....|
..*ext4*...../...*ext2*...../....*ext4*........../.....*ext4*......|........
swap .........|......ext4.........|
I can hibernate if I want too, cause I just might want to if I can and also
won't have to worry if I have room for movies.
This scheme would satisfy this - "Any directory tree which a user has write
permissions to, such as e.g. /home, /tmp and /var/tmp/, should be on a
separate partition. This reduces the risk of a user DoS..."
and, if I understand, address Magic Banana's main point as well, if more room
is needed in /usr, it's already there as long as / (/bin, /boot, /etc, /dev,
/lib, lib64, /media, /mnt, /proc /run, sbin, /srv, /sys, /usr, /var -
/var/log) doesn't exceed 16 GB there's room. And it seems like 16 GB should
last quite a while. I only wonder if I were to install games in /opt if 3.2
GB would get strained.
There might be a performance hit if a partition is bigger than it needs to be
but this scheme over all isn't very far over what I have now and I like it's
performance fine. I think Centos and Fedora may have each had 40 GB / and
they were fine also.
