CC RC1: Really low /overlay free space (~230KB) in 4MB device

Reported by: maverickp Owned by: developers
Priority: high Milestone: Chaos Calmer 15.05
Component: base system Version: Trunk
Keywords: Cc:


I'm using OpenWRT CC rc1, I done a full reset config: I intend to apply extroot with a USB drive to extend /overlay, but due to the low capacity available, is just impossible install necessary packages (block-mount, kmod-usb-storage, kmod-fs-f2fs).

My device is TP-LINK TL-MR3020v1 (4MB,squashfs fw)

FWIW I was able to get my TP-LINK TL-MR3020v2 (v2, not v1 as in original submit) to install block-mount, kmod-usb-storage, and kmod-fs-f2fs only after a full factory reset and those where the first tasks I did. Didn't leave much space though.

Also I was unable to actually use the f2fs partition as an overlay because the /sbin/block tool doesn't understand how to detect a f2fs filesystem type. The libblkid-tiny in OpenWrt fstools hasn't been updated with all the filesystem modules OpenWrt supports.
