Being cheap on / space usually will cause issues later on. Disk is cheap, yes even in laptops. ( Ok, maybe not SSD ). A good partitioning plan and using LVM can go a long way in helping with disk management. I would also recommend ( for a laptop ) avoid file system like XFS which can be grown, but not shrunk ( easily, for those about ready to tell me about using disk images to resize XFS ).

Relocating MySQL, Postgres and other RDBMS data directory and then symlinking it is nearly always a bad idea and strongly discouraged. If you need to move it from the default location ( which it should be moved from /var/lib ) then edit the appropriate config file and change the datadir accordingly.
