release 18.06 on RouterBoards (ar71xx/mikrotik): superfluous UBI volume
Username: Adolf Berthold
Origin: https://bugs.openwrt.org/index.php?do=details&task_id=1777
The sysupgrade-procedure of release 18.06 for RouterBoards (ar71xx/mikrotik)
(as contained in openwrt-18.06.0-ar71xx-mikrotik-vmlinux-initramfs-lzma.elf) creates
a superfluous UBI volume named “none”.
Details:
The function platform_nand_pre_upgrade() intarget/linux/ar71xx/base-files/lib/upgrade/platform.sh sets
“CI_KERNPART=none” to bypass the normal kernel-install-procedure.
This works, but causes nand_upgrade_prepare_ubi() in package/base-files/files/lib/upgrade/nand.sh
to creat an UBI volume named “none”, containing a (supposedly defective) kernel-yaffs2-image.
Used command :
sysupgrade -n -v
