changes to allow GPT BIOS boot partitions

2018-01-06T18:48:34Z

* Parted: Allow partitions to have no filesystem, for eg, GPT BIOS boot partitions. (API change) * Added rawPartition to PartSpec, for specifying partitions with no filesystem. * Added BiosGrubFlag to PartFlag. Note that man parted does not list the "bios_boot" flag, but I found it in its html documentation. Other flags may also be missing. This commit was sponsored by Boyd Stephen Smith Jr. on Patreon.

Grub.boots, Grub.bootsMounted: Pass --target to grub-install.

2017-12-21T04:12:01Z

This is to support eg, coreboot. The GrubTarget passed to Grub.installed is introspected to determine --target. If multiple grubs are installed, it currently doesn't pass any --target. Might make more sense to run grub-install repeatedly, but I don't know if that case is sane at all. The Xen -> "x86_64-xen" mapping is kind of arbitrarily chosen since there's a i386-xen available too. I don't know when that case would be used in any case though; chainPVGrub uses installed Xen, but it does not run grub-install. If this does become a problem, would probably need to split it into Xen64 and Xen32. Renamed BIOS to GrubTarget in passing to match grub's terminology; BIOS was kind of a joke term for this in propellor. This commit was sponsored by Francois Marier on Patreon.

That can take quite a while, so let the user know why propellor has stalled.

two diskimage edge case fixes

* DiskImage: Fix rsync crash when a mount point does not exist in the chroot. * Fix bug in unmountBelow that caused unmounting of nested mounts to fail. This commit was sponsored by Jack Hill on Patreon.

disk partition alignment

2017-12-20T21:10:40Z

Cheap flash drives need partitions aligned to 4 MiB in order to not be slow (and to avoid extra writes). And at least 1 MiB alignment is generally a good idea, and most people seem to think 4 MiB is for all drives. I noticed that Parted.partitioned does not do that; the first partition started at an offset of 1 MB, and subsequent partitions from where it ends. (The 1 MB offset came from the PartedVal PartSize instance, and note that it was not 1 MiB.) * Parted: Add an Alignment parameter. (API change) A good default to use is safeAlignment, which is 4MiB, well suited for inexpensive flash drives, and fine for other disks too. Previously, a very non-optimial 1MB (not 1MiB) alignment had been used. * DiskImage: Use safeAlignment. It didn't seem worth making the alignment configurable here. Alignment is implemented by offsetting the first partition's start position so it's aligned (making sure to leave room for the partition table). Each partition is then extended as needed so the next partition will start properly aligned. Note that parted rejects partition tables that don't fit in cylinder bounderies. Before, propellor let parted deal with the fine details of layout, so that was not a problem. Now it's possible to set some wacky Alignment not divisible by 512, or use Byte sizes for partitions and create a partition table that parted rejects. But, using safeAlignment and MegaBytes should always be safe. Also, this fixes a rounding bug in Parted.calcPartTable. It was rounding up to the nearest MegaByte when allocating remaining disk space, so returned partition table that was actually larger than the disk size.

partition table in Info

2017-11-19T19:21:53Z

Diskimage.imageBuiltFor: New property to build a disk image for a Host, using partition table information configured via the new properties hasPartitionTableType, hasPartition and adjustPartition. This lets Machine properties include eg /boot partitions that are known to be needed by the bootloader, and the user can adjust those partitions and add others.

Service: Avoid starting services when noServices is used.

2017-11-18T01:58:53Z

Reconsidered making services never run inside chroots, that seemed too potentially limiting. Using Info rather than checking policy-rc.d because it will also work outside of debian, but more because policy-rc.d has an extremely complicated interface and I didn't want to deal with it.
