Hi,
I'm reading documentation [1] for Fedora on a USB stick. The only option
to have a portable fedora on a stick seems to be by creating an overlay
FS and this certainly leads to getting out of disk space at some point.
I would really like to create Fedora on USB that I can plug anywhere and
work off it.
I was thinking that perhaps I can just install regular fedora on a USB
stick like I would do on a hard drive. Then it can be updated and used
just like any other Fedora machine. Perhaps disable persistent logging
and swap so that flash memory doesn't wear out.
One issue I presently know about is dracut. It creates by default images
that only support a specific hardware. i.e. if I install kernel on a
machine with an nforce disk controller, it will put in intird only that
module thus Fedora will not boot on a machine with AHCI controller.
Maybe this wouldn't matter when all things are on the USB drive but then
can there be a problem with different USB controller modules?
I was wondering if anybody tried that and has tips for greated portability.
Thank you,
Aleksandar
I have been doing this for several years, currently F27,
but only as a recovery Stick.
I just do a standard install but use a custom disk layout
using ext4 / partition - no LMV.
gdisk -l /dev/sda
Number Start (sector) End (sector) Size Code Name
1 2048 1026047 500.0 MiB EF00 EFI System
2 1026048 1028095 1024.0 KiB EF02 BIOS boot partition
3 1028096 3125247 1024.0 MiB 8300 Linux filesystem
4 3125248 19902463 8.0 GiB 8200 Linux swap
5 19902464 61800414 20.0 GiB 8300 Linux filesystem
I have recently been using a Corsair GT 32GB stick
Thanks a lot for the tip! I am also planning to start with a 32GB USB
3.0 stick. It looks like though that you are having EFI and BIOS mode
both supported. Would you share how did you achieve it?
This one would be much better
128GB Corsair Flash Voyager GTX USB 3.1 Gen 1 Type-A Pendrive,
Black, 460MB/s Read, 460MB/s Write, 33k/40k IOPS, PC/Mac
£67.99
My Fedora notes say this - not certain it is still valid - but I did it for F27.
dnf install dracut-config-generic - To force a generic initramfs
This installs a single file
/usr/lib/dracut/dracut.conf.d/02-generic-image.conf hostonly="no"
I have not done the following - I waited for a kernel update.
To force an existing kernel to use a "fully configured" initramfs file then
dracut --regenerate-all --force
NB this will regenerate and over-write all /boot/initramfs* file
Make copies first if required
