Just found this: http://www.tuxradar.com/content/how-install-linux-usb-flash-drive This is not the full story. Live CDs scan the hardware at boot time, and so are likely to be compatible with the most machines. Dracut can be configured to not default to the hostonly="yes" option (/usr/lib/dracut/dracut.conf.d/01-dist.conf in Fedora). So you can build an initial ram filesystem that has the same hardware capability as the LiveCD/USB. Live CDs must by necessity have a small footprint, which means there's more space for your files - or you can just buy a smaller, cheaper drive. Live CDs run as much as they can in RAM, which makes for better performance. USB3 flash drives are quite fast. A regular installation can also be configured to take advantage of the available RAM. Live CDs don't use swap. In Fedora, my Linux swap partition on a hard disc is recognized and used by a LiveUSB. One could also create a swap file on the USB drive, https://docs.fedoraproject.org/en-US/Fedora/14/html/Storage_Administration_Guide/s2-swap-creating-file.html With the large USB flash drives you have, a full installation may be your best and quickest solution. You should try it before dismissing the option. --Fred
Hi Fred, Follow up: My Live USB ran out of room, probably from cache files on the web browser. And the way that file system work (it won't give back space you delete), I went ahead and bit the bullet and installed a direct Fedora Core 21 to a flash drive. Initially I used LVM, but wiped when I found out how difficult that was to share files with. Now I am all straight ext4 partitions. (There is a way to mount LVM volumes, but what a pain in the neck!) And I used your /usr/lib/dracut/dracut.conf.d/01-dist.conf hostonly="no" I did wind up with a swap file on my flash drive, but it doesn't seems to slow things down. So far, after figuring out my add on USB 3 adapter was non-bootable, I have had it work flawlessly on two disparate computers. And, I think it might be a tad faster than the Live USB. The computer with native USB3 boots perfectly. And with the file system not giving back space, it was only a time before the stick was unusable. Breaking the 3GB persistence barrier would help, but only delay the inevitable. And, I even installed LibreOffice, so I can show crashed Windows users that their M$O (Microsoft Office) files are recoverable. My 16 GB USB 3 stick is now about 1/2 full. And, if I ever want to go larger, I can use clonezilla and gparted to copy to a larger drive. No more wiping and reinstalling. Do to all the incomplete documentation out there, getting the autologin to work was a pain in the neck. Anyone who wants my notes on the issue, drop me a line. -T -- livecd mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/livecd
