I used it at work twice and it was mostly ok with power failures, thing is you have to be careful if you are mounting it very early on boot if your embedded OS can bootloop fast after LFS is already mounted, because if you nuke it with a flurry of power fails it will break. For example if you have a battery you probably want to be sure you have a reliable measurement for SoC and enough juice to stay up before you mount LFS.
