I want to move my main system on Slack and want to get the partitions exactly right. I have installed Slack on a spare box with the intention of isolating root and preventing it from growing in size. What I did was:

/ 700MB
swap 1GB
/usr 15GB
/home 10GB
/var 1GB
/tmp 1GB

Q1. Now, I noticed that the /dev folder is the biggest one left. What goes in there and how large can it grow? Currently it is 288MB. A large chunk of root so I was thinking partition that as well.

Q2. What is /proc and how big can that one grow as well? Is it wise to partition this and what size?

Q3. How big can /var and /tmp grow and is 1GB too much considering long term usage?

Q4. Would the following be a good solution?

/ xMB
swap 1GB
/usr 20GB
/home 40GB
/var 512MB
/tmp 512MB
/dev 512MB
/proc 512MB
FAT32 2GB

Total 65GB + xMB

Q5. Regarding root in Q4, how big should I make root and what can bloat it beyod xMB?

Q6. I was going to make root the only Primary partition and the rest logical. Is there a problem with this?

Q7. What is the benifit in making a /boot partition and is it advisable? If so, how big should I make it?

Thanks in advance

After a bit more reading up I have another question

Q8. I will be using Slack for gaming among other things. I read somewhere that some games and other programs might install in the /opt folder. Is there a way to prevent them from installing in there and use /usr for all programs or do I have to make an /opt partition as well?

Q9. Last one, I promise. For now. Can I get away with only the root partition as a Primary or should I create any others as Primary?

cheers

Q1: it is static
Q2: /proc contains information about your computer, I don't think it will grow a lot after booting, files are created automaticly in /proc
Q3: /var - most log files, watch files that are not rotated automatic, it can grow quite big, logfiles, mail, etc
/tmp can grow during the usage of the computer and depends on what you are doing and the software you are using , I think 1 GB is a too small.
Q4: no, I would prefer this:
/home - 40 GB (good idea to make this a seperate partition
FAT 32 - 2 GB (whatever you want)
/ - rest to avoid all kinds of trouble
I don't see the point of all these small partitions. That way you are making your life more difficult than needed, and more partitions will consume more space. And what is the advantage ? I don't see any.
Q5: see Q4 and I don't understand your question, sorry ...
Q6: No that's fine
Q7: a seperate /boot partition can be left unmounted so your kernel is more safe (user errors, disk crashing) , but basicly it is what you want. 1 kernel will take about 2 MB so you can calculate how much space you want to address for it.
Q8: KDE packages in Slackware are installed in /opt. You could just create a symlink to /usr or /usr/local .
Q9: see Q6

You're welcome :P

Don't forget the swap partition

muchas gracias

Q7. So create a partition but leave it unmounted? Not sure how this is done.

Q8. Not sure about this either.

hmm

Now I get it at least. Partition the /home so that it can be scalvaged if something bad happens or if I want to upgrade to Slack 11 and stuff the rest in one big partition to avoid problems and housekeeping.

Q7: in /etc/fstab (example) :
Q8: If you are using only one big / partition it is not needed, otherwise you can create a symlink named /opt which points to /usr or /usr/local
