Subject: Change RO rootfs failed RF Kill Switch Status and Failed to start Run pending postinsts

Hi,

Apologize for the cross posting.

I am running kernel 4.19.75 on iMX6 customized device with WiFi and 4G
LTE, it was running well in an RW rootfs. After I have just changed
rootfs to RO UBIFS partition, it failed RF Kill and postinsts I
suspect both try write to the RO and failed, any advice how to fix it?
Despite it failed RF Kill and postinsts, it was still working.

[ 6.097762] UBIFS (ubi0:2): UBIFS: mounted UBI device 0, volume 2,
name "rootfs-volume", R/O mode
..............
[ 6.151932] VFS: Mounted root (ubifs filesystem) readonly on device 0:13.
.................
[ OK ] Listening on Load/Save RF Kill Switch Status /dev/rfkill Watch.

Thank you.

Kind regards,

It also seems mwifiex_sdio tried to write to RO rootfs and failed and
triggled RF Killm, does mwifiex_sdio needs some system directories for
RW?

Failed at step STATE_DIRECTORY spawning /lib/systemd/systemd-rfkill:

How should I fix it?

Was the problem to write to /var/log, the /var/volatile does not have a log?

All system mount is the same as the original RW rootfs, did both write
to none standard RW system mount?

Here is defined system mount in fstab:

proc /proc proc defaults 0 0
devpts /dev/pts devpts mode=0620,gid=5 0 0
tmpfs /run tmpfs
mode=0755,nodev,nosuid,strictatime 0 0
tmpfs /var/volatile tmpfs defaults 0 0


Here is the mount:

# mount
ubi0:rootfs-volume on / type ubifs (ro,relatime,assert=read-only,ubi=0,vol=2)
devtmpfs on /dev type devtmpfs
(rw,relatime,size=84564k,nr_inodes=21141,mode=755)

How should I fix it?
