Fedora 24 Live Workstation may be installed on a 2 GB USB device using the following options with livecd-iso-to-disk on a single, terminal or console command line :.
The above configuration would allow space for the home folder, the operating system, and a minimal amount on the device root. But with a larger capacity device, one may allocate the resources to suit the anticipated use, as described above. The actually available and allocated physical disc space for the root filesystem is determined by the size of the device-mapper overlay file and can only be queried by the dmsetup status command see below.
Fedora LiveOS uses the Device-mapper service of the Linux kernel to manage the file stores on the device. This is the same service that is used by Logical Volume Manager to provide disc partition services.
One critical limitation, mentioned above, is that the LiveOS persistent overlay is an allocate-once, fixed size, file space. This is related to its use of device mapper snapshots to combine a read-only file system image copied from the compressed SquashFS.
With this mechanism, no physical storage space of the read-only, base filesystem can be reused. The apparent free space in the virtual root filesystem as reported by the df command will increase, but this additional space is not physically available; however, when a new or changed file is deleted, the new or changed sectors only in the overlay are available for reuse, but, unfortunately, the count of allocated sectors does not change, so one cannot be certain of the availability of free physical space after arbitrary changes to the root filesystem.
The status of the space allocated for persistent storage in the snapshot overlay file may be tracked with the device mapper dmsetup status report. For example, dmsetup status live-rw may return.
The final number is the metadata sectors allocated, and the number before snapshot is the apparent size of the virtual filesystem. Where long-term usage of a LiveOS image is anticipated, special attention to overlay consumption is advised. I created a second user and switched back and forth throughout the day while testing the Fedora system for this review.
Instead of losing your work or having to close everything out when another family member wants to get to their email, just use the fast user switching and each user is happy. Fedora 7 includes a couple of SELinux tools that are new or not previously enabled by default in other Fedora releases: a new GUI admin tool system-config-selinux and a troubleshooting tool selinuxtroubleshoot.
Many sections of the admin tool require a fair understanding of SELinux. As it is, the tool only sports an About dialog under the Help menu. One of the features in F7 is a rewritten FireWire stack for the kernel. Not more than three hours after installing Fedora, my system beeped twice and locked up tight. I rebooted to see if I could reproduce the problem. After about two hours, once again, I received a couple of console beeps and the machine locked up.
I checked the system logs and noticed an error about a hardware problem on the PCI bus. I thought the problem might have been a dying drive — until I connected the drive to my Ubuntu desktop and was able to access it with no problem. After getting all my data off the drive, in case the drive really was going wonky, I kept an eye on it and copied several gigabytes worth of files back and forth to see if I could cause a failure or even find any error messages.
This should be done as a normal user on a workstation:. The below commands assume that you have already connected the USB drive to be formatted. Be careful that you do not format the wrong drive! This is just one method of loading iPXE.
You could install syslinux directly on your workstation. The best option depends on your environment. Photo by Chris Yates on Unsplash. Perhaps I am a lay man or it is just for fun! But I hear you. I have external backup drives. I also have internal drives a through f.
I often want to install a Linux ISO on one of the b through f drives.
