Hi,

Is it advisable to replicate the system partitions as well as the data 
partitions (/var, / and /usr)?

Both of my machines which I intend to use in the replication are i386 
based (Athlon processors) and dont have any special hardware. They are 
_not_ hardware clones of each other.

The advantages I can think of are
1. System config changes are synced across as well, so the secondary 
node is upto date configuration wise.
2. Less administration as a result of the above.
3. No need to relocate and make symlinks of directories like 
/var/lib/nfs etc..

Disadvantages:
1. Accidental mangling of config files on primary will be 
instantaneously transferred to secondary.
2. Unknown demons that will present themselves when I install new software.

Thanks,
Faisal
