# ALWAYS use UUIDs to map drives, NEVER dev names (i.e. sda sdb) # sda/sdb etc. enter into race conditions on boot (vmware vdisk init times maybe?). so this mount command will get stuck trying to mount an already mounted drive (grub grabbed it) and your boot will hang, then your secondary mount will timeout and fail silently.

NFS has caching by DEFAULT, and we're going to keep using it but the defaults are huge, so I'm turning them all to 1 second. actimeo=1` alone is sufficient. It sets all four values (`acregmin`, `acregmax`, `acdirmin`, `acdirmax`) to 1.
