Dear all,
I've once more tried to build up a riscv32 linux install in a qemu-riscv32
usermode systemd-nspawn, and am running into the same problems as some time
ago...

The problems manifest themselves mostly in bash; if I replace /bin/bash
with a static x86-64 binary (in the tarball as /bin/bash.amd64), bypassing

Bash tests apparently indicate that argv[0] is overwritten, and that
reading through a pipe or from /dev/tty fails or loses data.
Apart from the bash testsuite failing, symptoms are as follows:
* Something seems wrong in the signal handling (?):
If it is wrong for signal handling and for 32-bit, I guess it may be
fixed by this patch

And this patch has been merged into master branch yesterday.
May be you can have a try based on the master branch.
Thanks,

--- our package manager (bash/python combo, there bash) hangs reproducibly at
one point.
--- when I run a console program and try to background it with ctl-z, it hangs
(only the first time per bash instance, it seems)
repeated ctl-c gets me back to the shell, then the program is in the

Any advice or debugging would be appreciated.
If we get this running then I can set up regular riscv32 Gentoo stage builds
within a week. [*]
Thanks in advance,
