[arch-general] Migrating /var to a different partition

[Sri Krishna]

Hi,

I'm doing a clean install of Arch on a new computer, and during the install
I'd already set aside 2GiB for the /var partition.

Except I forgot to add it to fstab before I exited chroot, and booted into
Arch and installed a DE etc. Now two days later I realize that Arch has
already created a /var directory on the / partition. How do I migrate /var
into the partition I'd originally created for it?

Is it as simple as adding a line to fstab and rebooting?

Thanks,
Krishna
