installer: Remove logical devices.
If a device contains an active logical volume, BLKRRPART will report that the device is busy. This will cause this device to be filtered by "non-install-devices" procedure, which is not desired. Make sure to deactivate all logical volumes before device probing. Fixes <https://issues.guix.gnu.org/42683>. * gnu/installer.scm (installer-program): Add lvm2-static to the inputs. * gnu/installer/parted.scm (remove-logical-devices): New procedure, (init-parted): call it.
