I cannot bootstrap 8.0.1-rc2 with 8.0.1-rc1
unrecognised flag: -this-unit-id
Usage: For basic information, try the `--help' option. https://buildd.debian.org/status/fetch.php?pkg=ghc&arch=arm64&ver=8.0.0.20160204-1&stamp=1454952602
I didn’t quite follow the Cabal issues on the tickets list, so this might be known, but it certainly should not happen.
Or is this a problem with 8.0.1-rc1 and I should just avoid that version somehow, and it will bootstrap with 8.0.1-rc2 just fine?
Yes, this should merely be a problem with -rc1. Edward Yang did some cleanups of the package-system command-line flags in -rc2. The original goal of this was to ensure that users with older Cabals aren't surprised with the terrible errors that they are currently faced with [1]. Sadly this didn't quite get resolved in -rc2, however. See D1892 [2] for one possible future direction for putting this issue to rest.
