- Subject: initramfs-tools: mount fails with rootfstype=auto

Package: initramfs-tools
Version: 0.130
Severity: normal
Dear Maintainer,
I encountered a strange problem mounting the rootfs with a freshly debootstrapped system.
Note: possible duplicate of #845302 but due to the details I found it probably warrants its own topic.
Steps:
- used debootstrap with --variant=minbase to create an armhf rootfs
- added custom packages such as vendor kernel, systemd, initramfs-tools
- created extlinux.conf to boot
- bootargs: root=UUID=... rootfstype=auto rootwait
Observations:
- root=/dev/mmcblk0p1 rootfstype=auto: fails
- root=/dev/mmcblk0p1 rootfstype=ext4: works
- root=UUID=... rootfstype=ext4: works
How did I find this?
I added "set -x" to
- /usr/share/initramfs-tools/init
- /usr/share/initramfs-tools/scripts/init-bottom/udev
The serial console then finally revealed what is going wrong.
When it fails (rootfstype=auto):
+ [ auto != unknown ]
+ mount -r -t auto /dev/mmcblk0p1 /root
mount: No such device
When it works (rootfstype=ext4):
+ [ ext4 != unknown ]
+ mount -r -t ext4 /dev/mmcblk0p1 /root
[ 9.979060] EXT4-fs (mmcblk0p1): mounted filesystem with ordered data mode. Opts: (null)
So I see two solutions:
- If rootfstype=auto, and the actual type is known through a previous call to blkid, e.g. while running fsck, use the known type
- fix the mount command to deal with type auto
I am submitting the full boot logs by email as follow-up.
Yours sincerely
Josua Mayer
