Trials and tribulations are good for the soul. ;-) Except when they
happen to me. :-D

I keep more that one active version of Fedora around, so don't really
use rescue mode. When I have a problem, I just boot another version of
Fedora to do any maintenance required. Because of that, I don't really
have any familiarity with rescue mode, but I think that if you are in
rescue mode, you have to mount the original root system my using
mount /dev/sda? /mnt/Sysimage
where /dev/sda? is the root device of the system you are trying to
rescue. You then have access to that file system. It might not be
Sysimage, so you could do an ls /mnt to find what it actually is, or
create a directory under mnt, and mount there.

If the kernel recognizes the device, then lsblk -f should show the file
system type in the output. From the man page for lsblk,
"""
Note that lsblk might be executed in time when udev does not have all
information about recently added or modified devices yet. In this case
it is recommended to use udevadm settle before lsblk to synchronize
with udev.
"""
A recently mounted usb device might meet those criteria, and be missed
unless you run udevadm settle.

I think that is only available from the dracut shell. It's my
understanding that rescue mode != dracut shell.

I think the lsblk command above will do that.
