I looked at the strace output you provided, and didn't find any evidence
of a missing file, which I doubt would lead to the error message "unable
to fork" anyway.  The short excerpt that you quoted in your earlier mail
showed the failure to find "/etc/ld.so.preload", but that's expected,
and does not indicate a problem.  The problem might be happening in the
child process (/home/sdb/.guix-profile/libexec/git-core/git), so adding
the -f option to strace, i.e. "strace -f git pull swedebugia", might
yield more useful information.

If I'm not mistaken, "unable to fork" more likely indicates a lack of
available resources, possibly due to configured resource limits (see
ulimit(3) and the 'ulimit' bash builtin, e.g. try "ulimit -a").
Otherwise, I guess it could be due to restrictions imposed by the use of
a security framework.

       Mark
