Re: [PATCH v3 4/4] dpkg-base: Update git alternates

[Henning Schild <henning.schild@siemens.com>]

Well i thought about this again. This is a very nasty workaround for a
problem this actually is in bitbake.

https://github.com/openembedded/bitbake/blob/ebce92bf8d71f8a6e8af1c6cf6ba335faf9d67c8/lib/bb/fetch2/git.py#L179

That problem should be fixed in bitbake, if they accept patches. The
"-s" needs to depend on some condition.

For Isar i would tell people to fetch tarballs from git servers and
avoid git://.
