A lot of my installs are 512MB-1GB : /boot 2GB : / 2-4GB : /usr, lvm 2-4GB : /var, lvm --- optional --- XGB : /usr/local, lvm XGB : /var/something for apache or mysql or storing penguins, lvm /boot is never in a lvm and I usually do not put / in a lvm either; the rest are always in lvm so I can move and resize them as needed. And even that might be way too much: My kvm-based vm host (centos 6.4): [root at vmhost ~]# df -h Filesystem Size Used Avail Use% Mounted on /dev/sda2 1.9G 638M 1.2G 35% / tmpfs 7.7G 0 7.7G 0% /dev/shm /dev/sda1 472M 149M 299M 34% /boot /dev/mapper/vmhost_vg0-usr 4.0G 1.5G 2.4G 38% /usr /dev/mapper/vmhost_vg0-var 4.0G 1.2G 2.7G 30% /var fileserver:/home/raub 197G 163G 35G 83% /home/raub [root at vmhost ~]# My nagios/rsyslog thingie: [raub at scan ~]$ df -h Filesystem Size Used Avail Use% Mounted on /dev/vda2 2.0G 675M 1.3G 36% / tmpfs 246M 0 246M 0% /dev/shm /dev/vda1 504M 106M 373M 23% /boot /dev/mapper/nagios_vg0-usr 2.0G 584M 1.3G 31% /usr /dev/mapper/nagios_vg0-var 2.0G 440M 1.5G 23% /var fileserver:/logs 20G 651M 19G 4% /var/log/syslog [raub at scan ~]$ As you can see, even 2GB is overkill for my root partition. Remember: if you are using lvm you can move the other partitions to another drive or raid without rebooting. And, you can set all that during the install without losing your sleep. > But as a generic question: is there a way to get the installer to put > some top-level directories into subdirectories on a different volume > so they share space but aren't part of the root volume?
