[gentoo-user] Partitions - last questions...

[Tanstaafl <tanstaafl@libertytrek.org>]

Ok, this is the last question I need to answer for myself before 
installing a final version of my new virtualized gentoo server...

I'll be using the following partition layout:

/boot (ext2), 100M
/swap, 2G
/ (ext4), 40G

then on LVM

/tmp (ext2), 5G? <- how big?
/var/tmp (ext2), 5G? <- how big?
/var/log (ext4) <- size? should I even have this separate?
/var (xfs), 750G
/snapshots (xfs), 10G? <- for lvm snapshots of /var for backups

I'm not using a separate /home because there are no system users beyond 
my admin user (and the system user accounts)...

So - first, is 5G way too big for the two /tmp dirs? I have lots of 
space, but hate waste

This mail server is not all that busy, and the backups only take about 
an hour, so I guesstimate that there won't be more than about 100-300MB 
of changes at the *extreme* outside of the envelope, so the 10G is most 
likely extreme overkill... but I'll know soon enough, and besides, I've 
got plenty of disk space to play with.

One question... I have some MySQL databases running on this system too, 
for my userdbs, and on the new server, SOGo (groupware)...

Is it recommended to incorporate scripts to perform dumps of the dbs, or 
is the lvm snapshot reliable enough for backing these up in their raw state?

Thanks as always for comments/suggestions/criticisms...
