Re: [fedora-arm] initial setting of root password is not working

Hi Guys, I recently got Fedora@22 running on my ARM OEM Board ( TI AM3352 OMAP family SoC). As there is no micro-SD socket on the board itself, I followed the installation instructions from here /https://fedoraproject.org/wiki/Architectures/ARM/F22/Installation/ except that after I had xzcat'd the minimal image to an SD card (on the host!). I then blatted the whole thing out again via dd onto the board's emmc memory. Then rebooting the board into u-boot, I used the following commands (thanks Peter Robinsom@list) to boot into linux. setenv bootargs console=${console} root=LABEL=_/ ro rootwait ext4load mmc 0:1 0x80300000 vmlinuz-4.0.4-301.fc22.armv7hl ext4load mmc 0:1 0x81600000 uInitrd-4.0.4-301.fc22.armv7hl ext4load mmc 0:1 0x89300000 my-device-tree.dtb bootz 0x80300000 0x81600000 0x89300000 Great stuff! Everything boots up, welcome to F22 etc. Then the initial set up (text) runs and I set a root and user password. After this has seemingly all worked fine, I'm asked to use my new credentials to log in. The password I've just created is then roundly rejected as an invalid login! My first thought was that I should have used rw rather than ro in my bootargs, so I repeated and had exactly the same result. I then thought that on the host machine I could just write to /etc/shadow on the root file system __ on the SD card image. For the root password I generated an MD5 checksum string and put that in as the root password. This worked fine on Ubuntu when I tried something similar as an experiment - a new user effectively had 'password' as a password. In this context, I hoped the same approach would in effect pre-load the root password when the whole image was dd'ed out to the emmc. Consequently I could avoid setting any password in initial set-up - no luck, exactly the same result!! The initial setup is being used in a slightly unusual context - not booting from sd card but from the onboard emmc so that may be a problem. Unfortunately I can't effectively debug what's going wrong here because I can't get in without a root password. I can break into single user mode but that doesn't give me root user privilege. This is very frustrating as I don't even want a root password whilst in development and I'm sure there's some idiotic obvious thing I'm missing to set the root password. Any thoughts ?! Thanks in advance. Andrew
