@EdwardNedHarvey Then you are going to be surprised ... Please understand we are talking about ZFS dataset names here.

@EdwardNedHarvey Have a look to docs.oracle.com/cd/E36784_01/html/E36835/gbcpt.html which is quite authoritative.

comment Allowed and safe characters for ZFS filesystem in FreeBSD
@EdwardNedHarvey I'm afraid you are misunderstanding the OP question. This is not about file names like in your touch example but about ZFS file system (a.k.a. datasets) names, i.e. the ones you use with zfs create pool/filesystemname.

comment What dev folder allows you tell the OS to cache something?
Not in RAM but in virtual memory. If you have a swap area configured, that makes a big difference.

comment How do you move files into the in-memory file system mounted at /dev/shm
Beware that tmpfs based file system, available at least on Linux, BSDs and Solaris are not RAM disks. They store the files on virtual memory, not (directly) on RAM. They are then more efficient and far more flexible than the OSX RAMdisk.

comment What dev folder allows you tell the OS to cache something?
Note that strictly speaking, tmpfs is not RAM-backed but Virtual-Memory-backed, i.e. the files blocks are stored either in RAM or on disk (in the swap area unless of course you have none). That gives tmpfs several advantages compared to traditional RAM disks implementations.

comment What happens when a tmpfs is full and no swap space is available?
You already are kind of out of swap with 5 GB stored in tmpfs and a 4 GB swap. The worst case behavior starts with RAM shortage. What will happen depends on the OS and its settings. With Linux, the OOM killer might play a role here.
