I'm reading documentation  for Fedora on a USB stick. The only option

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.
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

I have recently been using a Corsair GT 32GB stick
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
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
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
