Move home to another partition
From MEPIS Documentation Wiki
MEPIS installer doesn't have the option to crate home on another disk, however it's easy to set the home on a different disk or partition.
- Move the "username" folder to the desired partition
- Add the line in the static portion of /etc/fstab:
/dev/partition_name /home partition_type defaults,noatime 0 2
Where "partition_name" and "partition_type" are the actual name and type of the new partition.
