Subject: Generic way to detect qemu linux-user emulation
Date: Tue, 18 Mar 2025 11:18:13 +0100 [thread overview]
Message-ID: <mvm1puuiqvu.fsf@suse.de> (raw)
Is there a generic way for a program to detect that is it being run
inside the linux-user emulation?
The purpose for that would be to work around limitations of the
emulation, like CLONE_VFORK being unsupported. For example, python >=
3.13 needs to avoid using posix_spawn in that case, because the
emulation of CLONE_VFORK as a true fork makes it impossible for it to
report errors back to the parent process.
