From 57064ac9ccd8a3783789d11feb5a51351cd924bf Mon Sep 17 00:00:00 2001 From: Ricardo Neri Date: Fri, 10 Jul 2015 17:41:03 -0700 Subject: [PATCH] bootimg.bbclass:iso: determine the -iso-level only if there is a rootfs It may be possible that some bootable images do not use a rootfs; this may be the case if the bootable image utilize only an initrd for all its needs. If there is not rootfs, the size calculation will fail. Furthermore, given that the iso9660 conformance level is determined using the size of rootfs, it makes sense to not make the calculation if there is not such rootfs.
