/opt is the traditional space for third party installs, although I believe /srv is the 'correct' place according to lsb?
/var is for data, not installs. you can always install it elsewhere through symlinks, I think in the past I've done that without problems. and through the admin interface you can relocate the mailstores to wherever you want. there's been some call in the past for the stores to be in /var by default, as zimbra occasionally has the habit of rm -rfing /opt/zimbra without warning. |
