Hey, > * gnu/installer/parted.scm (auto-partition!): Avoid removing logical > partitions twice. I was able to reproduce the issue by creating an extended partition containing a single logical partition using the manual partitioning tool then, the automatic one right after. It resulted in a segfault, which is fixed by your patch, that's a very nice catch! Pushed as 4989f6acff3b3fcfbd9dde3e3c2767bd2cd6d49e. Thanks, Mathieu
