In GhostBSD, which is based on FreeBSD, the approach to creating and using RAM disks is quite similar to Linux but with some differences in the commands and configuration files used. The `tmpfs` filesystem type is also supported in FreeBSD, making the transition easier.
Here's how you can achieve the equivalent setup in GhostBSD:
1. Creating the Mount Point: The command to create a mount point remains the same. You can use:
sudo mkdir /mnt/tmpfs.ramdisk
2. Adding an Entry to /etc/fstab: The format for the `/etc/fstab` file in FreeBSD (and by extension, GhostBSD) is similar to that in Linux, but there are slight syntax differences. The equivalent entry in GhostBSD's `/etc/fstab` for your Linux `tmpfs` line would be:
Key differences to note:
- The options are largely the same, but `nodiratime` is not a recognized option in FreeBSD's tmpfs. FreeBSD's tmpfs does not distinguish between access times for directories and files, so you don't need an equivalent for `nodiratime`.
- The options are comma-separated as in Linux, and the basic syntax of the fstab line is the same.
- Ensure you use `rw` to denote that the filesystem is mounted read-write.
3. Mounting the Filesystem: After adding the entry to `/etc/fstab`, you can mount all fstab entries with the following command (or just reboot):
sudo mount -a
This command mounts all filesystems specified in `/etc/fstab`, including your `tmpfs` RAM disk.
This setup should give you a RAM disk on GhostBSD that functions similarly to your Linux setup, with a size of 500MB, mounted at `/mnt/tmpfs.ramdisk`, and with no device and no set-user-ID or set-group-ID bits.
