I have a 256 GB SSD and a 1TB HDD in my laptop. I want to dual-boot Kubuntu 20.04 with Windows 10. Please explain what exactly do /var and /tmp do, because I need to do some web developing and want to know whether I should make separate partitions for them. Also, to save space on the SSD, can I mount /home, /var etc. on the HDD, without a significant increase in boot time? I heard that root partition will have to wait for mounting from HDD, which will increase boot time. Besides, should I make separate /opt and /usr, too. My current planning is: 11GB swap in SSD, 45GB root partition in SSD, 1GB /boot in SSD, and 50GB /home in HDD. I have also heard that separate /boot partition is not needed in SSD. So please guide me. Thank you!!

- It's better to have a boot partition for Linux on your SSD and 512MB will be enough.
- It's OK to have /home on your HDD (that won't slow down boot significantly).
- If you don't expect to have many gigabytes worth of MySQL (or any other DB) data there's no need to have a separate partition for /var. Likewise for /opt. It's not clear what you'll be running.
Backup your EFI System partition before installing Linux just in case.

A you have a Windows recovery drive, you can probably omit this step. Jun 16, 2020 at 15:35

Can I somehow use symlinks in case I need space on / and var and tmp are taking too much? Jun 16, 2020 at 15:58
