- gzip in busybox 1.29.1 doesn't seem to use compression anymore, with -1 and -9 both coming out to the same size, generally dramatically larger than previously resulting in boot-new.img exceeding the partition size on some devices so then failing the check. e.g. 28mb ramdisk.cpio -> 11.2mb ramdisk.cpio.gz in 1.28.4, is now 20mb in 1.29.1 thanks nathanchance for reporting
