For my SOHO LAN environment, I build my Debian Wheezy systems on a 16 GB
SSD with 10% over-provisioning [1]. The installer defaults to MBR
partitioning [2], which is what I prefer. Here are my notes from the
last laptop build:
Partitioning method manual
partition #1
size 0.5 GB
type primary
location beginning
use as ext4
format yes
mount point /boot
mount options defaults
label t7400_boot
reserved blocks 5%
typical usage standard
bootable flag on
partition #2
size 0.5 GB
type primary
location beginning
use as physical volume for encryption
encrypt method device-mapper
encryption aes
key size 256
IV algorithm xts-plain64
encryption method random key
erase data yes
bootable flag off
partition #3
size 13.4 GB
type primary
location beginning
use as physical volume for encryption
encrypt method device-mapper
encryption aes
key size 256
IV algorithm xts-plain64
encryption method Passphrase
erase data yes
bootable flag off
Encrypted volume (sdb3_crypt) - 13.4 GB Linux device-mapper
use as ext4
mount point /
mount options defaults
label t7400_root
reserved blocks 5%
typical usage standard
The only thing I'd change today would be "Encrypted volume (sdb3_crypt)"
-> "use as btrfs".
I have run systems without swap in the past, but found that they crashed
when memory usage was heavy.
When a workstation system drive is an SSD larger than 16 GB, I often
create a "scratch" partition with 90% of the remaining space that I can
use for applications that create large temporary directories/ files
(such as the 'Lives' video editor).
I put my "bulk" data on a file server with TB+ HDD's.
This works great when I'm at home, but not so great when I go remote
with my laptop. Solution ideas include:
1. VPN.
2. A FOSS equivalent of Microsoft's Offline Files/Client Side Caching:
