Is there a way to get /home, /var, and /opt installed as directories on that other "one big partition"? /var in particular has an odd mix of OS and 'your' data and logs that may turn out to be big. And you may not know ahead of time what to allocate for it as a separate mount point.
Here at work, /home is *always* NFS-mounted. Even so, I'd think 250G is easily big enough for / to include /var, even with a moderately large d/b there.
I think 250G is overkill unless you have need for all that space. 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@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@vmhost ~]#
My nagios/rsyslog thingie:
[raub@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@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? You can do each as a separate mount point, but sometimes I want the effect you get with symlinks - which involves some awkward juggling for system-installed directories that already have contents.
