Update to baselayout-1.8.6.8-r1. After rebooting macihine, the root device when running "df", i.e., what is in /etc/mtab will no longer show the actual device name that the "/" directory is mounted in. Reproducible: Always Steps to Reproduce: 1. emerge -u baselayout from previous version 2. reboot machine 3. root device will be displayed as /dev/root vs. /dev/hda1 or whatever the real device is. Expected Results: Correct name for root device should be shown in /etc/mtab. I was able to fix this problem in /etc/init.d/checkroot by commenting out the lines below: # Create /etc/mtab grep -v 'rootfs' /proc/mounts > /etc/mtab Adding these lines to /etc/init.d/checkroot before the ones pertaining to removing stale backups of /etc/mtab solved the issue (I'm sure other methods may also work): # Clear mtab > /etc/mtab # Enter root filesystem into mtab mount -f /
i'm pretty sure its a devfs thing
This is actually an old problem with the content of /proc/mounts. You can see many entries on this subject in the online database at google.com: http://www.google.com/search?q=/dev/root%20/proc/mounts&ie=UTF-8&oe=UTF-8 The checkroot script is taking the content of the /proc/mounts pseudofile and grepping out the line with rootdev in it, and replacing the contents of /etc/mtab with vague information. The kernel generically refers to the root device as /dev/root in this file, due to some decisions made by the kernel programmers some time ago. I'm not sure if this issue is related to using devfs, which I am, but someone who is not should be able to see if it applies without devfs.

Has this made it to stable yet? If it hasnt, do you know what version of baselayout it will be in so I will know when its safe for me to upgrade my server.
