Subject: Re: Cannot mount vfat filesystem, dmesg says "codepage cp437 not found"
To: ~alpine/users@lists.alpinelinux.org

I have identified the problem.

My goal is to run Alpine without any disks.  (I had assumed this would
be "diskless mode".)  I want to boot from a USB stick, and then be
able to remove the USB stick after bootup has completed.

I had assumed that the Alpine installation .iso would run in diskless
mode.  Consequently, after boot, I did the following:

umount /.modloop
umount /dev/sdb

After the above two umount commands, attempts to mount a vfat
filesystem result in the "Invalid argument" error.

The Alpine documentation discusses "diskless mode" here:

https://wiki.alpinelinux.org/wiki/Alpine_setup_scripts#diskless_mode

However, it appears that even after you run setup-alpine and select
disk=none, the following are still true:

1) /.modloop is mounted.
2) The installation media (which backs /.modloop) is still required.

Are there any guides or tutorials that explain how to configure Alpine
so that all disks can be removed after boot?

Thank you,

Parke
