[bitbake-devel] [PATCH 1/1] bitbake: Disable pseudo in runfetchcmd()

[Peter Kjellerstedt]

If a fetcher, e.g., git, is run when pseudo is active it will think it
is running as root. If it in turn uses ssh (as git does), ssh too will
think it is running as root. This will cause it to try to read root's
ssh configuration from /root/.ssh which will fail. If ssh then needs to
ask for credentials it will hang indefinitely as there is nowhere for it
to ask the user for them (and even if there was it would not access the
correct private keys).

The solution to the above is to temporarily disable pseudo while
executing any fetcher commands. There should be no reason for them to be
executed under pseudo anyway so this should not be a problem.
