![]() ![]() The project is supported and promoted by the FreeBSD Foundation.įreeBSD maintains a complete system, delivering a kernel, device drivers, userland utilities, and documentation, as opposed to Linux only delivering a kernel and drivers, and relying on third-parties like GNU for system software. The first version of FreeBSD was released in 1993 developed from 386BSD and the current version runs on x86, ARM, PowerPC and RISC-V processors. Unix shells: sh or tcsh (user-selectable)įreeBSD License, FreeBSD Documentation LicenseįreeBSD is a free and open-source Unix-like operating system descended from the Berkeley Software Distribution (BSD). Monolithic with dynamically loadable modules Note that this requires that the drive is already connected to your computer and you need to replace /sda/sda5 in the examples accordingly.Servers, workstations, embedded systems, network firewalls To find the UUID of a disk use either blkid or if not available udevadm. Whenever the disk with UUID 2a2a2a2a-2a2a-2a2a-2a2a-2a2a2a2a2a2a is plugged into your computer, it will be mounted under /var/autofs/removable/usb. ![]() ![]() This option does not require you to create named /dev entries for your devices with udev.Įdit the file auto.master as described above.Ĭreate your file that contains the individual disks like this: etc/auto.removable: ipod -fstype=vfat :/dev/ipodĮhd7 -fstype=vfat,uid=1000,gid=1001 :/dev/ehd7įirst field denotes mount point, second field has options (man 5 autofs) and the third field is the device to mount. Last field lists options for this directory: timeout=2 is the minimum timeout until items are unmounted. Second field denotes the configuration file for this entry. The first field is the path under which autofs mounts the devices. etc/auto.master: /var/autofs/removable /etc/auto.removable -timeout=2,sync,nodev,nosuid We need to configure it to mount the devices. Lrwxrwxrwx 1 root root 4 Apr 13 18:29 /dev/ipod -> sda2īy default autofs mounts devices in /var/autofs/.

So, use "udevadm info" instead: sudo udevadm info -query all -path /sys/block/sdb/sdb5/ -attribute-walk $ udevinfo -a -p /sys/block/sdb/sdb5/ | grep model For example, I'm configuring my external USB HDD, which normally appears as /dev/sd? (?=a,b,c.) and I want to be able to identify it uniquely. Plug in the device you're configuring and check its info using udevinfo command. You need to find out some details of the device in question for udev to recognize it properly. You need to be running a 2.6 kernel for udev to work. Here's a short introduction on how to automount various external devices, for example USB sticks, memory card readers, external hard disks etc. NB This information is likely outdated, usbmount does much of this automagically for most use cases. ![]()
