So I got it to build, but now I'm wondering about changing userdata or data to ext4. In fstab.qcom, there are 2 /data mountpoints, one with f2fs and the other with ext4. Do I just delete the f2fs entry?

/dev/block/platform/msm_sdcc.1/by-name/userdata  /data          f2fs    nosuid,nodev,noatime,rw,inline_xattr                                                          wait,check,formattable,encryptable=footer
/dev/block/platform/msm_sdcc.1/by-name/userdata  /data          ext4    nosuid,nodev,noatime,noauto_da_alloc,journal_async_commit,errors=panic                        wait,check,formattable,encryptable=footer

So I'm running into issues building Halium for jfltexx.

When I ran mka mkbootimg, here's what I got:

halium/hybris-boot/Android.mk:69: ********************* /boot appears to live on /dev/block/platform/msm_sdcc.1/by-name/boot
halium/hybris-boot/Android.mk:70: ********************* /data appears to live on /dev/block/platform/msm_sdcc.1/by-name/userdata

Here are the list of commands I ran (pretty much followed the steps), and their output. Hope you can help me.
