Subject: [RAUC] [RFC 0/3] Fix slots with nodev mounts
Date: Fri, 10 May 2019 11:48:03 +0200	[thread overview]
Message-ID: <20190510094803.GA29451@lenoch> (raw)

Hi there,

this is just an attempt to make rauc work with nodev mounted slots.
It is based on https://github.com/rauc/rauc/pull/406 where first
patch in the serie is meant to be squashed there.

Second patch then implements matching against ubi:<vol_name>
device naming scheme and can be easily extended. Now with
$ cat /proc/mounts 
ubi0:rootfs0 / ubifs ro,relatime,assert=read-only,ubi=0,vol=0 0 0
[strip]
It is able to correctly find slot and use it as seed slot for casync:
$ rauc status
Compatible:  Foomatic System
Variant:     
Booted from: rootfs.0 (system0)
Activated:   rootfs.0 (system0)
slot states:
  rootfs.1: class=rootfs, device=/dev/ubi0_1, type=ubifs, bootname=system1
      state=inactive, description=, parent=(none), mountpoint=(none)
      boot status=good
  rootfs.0: class=rootfs, device=/dev/ubi0_0, type=ubifs, bootname=system0
      state=booted, description=, parent=(none), mountpoint=/
      boot status=good

Third patch is again just a preview - r_mount_slot should be fixed
instead. I'm assuming anything having ext_mount_point set is already
mounted there, thus only bind mount makes sense here. Correct?

Please review, I'd like to have patch 1 and (rewritten) patch 3
merged for v1.1 milestone :)

Thank you,
	ladis
