Hmph, what's the sequence of events? You let "git new-workdir" to
create a cheap copy of a working tree and then? When new-workdir
returns, you already have a functional working tree with .git/
directory (in which there are many symbolic links). So who wants or
needs to run "git init" there in the directory in the first place?
Is the problem being solved that running an unnecessary "git init"
in an already initialized repository does an unnecessary filemode
check?
If that is the case, I am not sure if asking "is it a symlink?" to
avoid the filemode trustability check is a good approach. At that
point in the code you are patching, we have already determined if we
are running the "git init" in an already initialized repository
(i.e. "reinit"), so shouldn't we be basing the decision on it
instead?
I see that in a later part of the same function, we test if the
filesystem supports symbolic links but do so only when we are
running "git init" afresh. Perhaps the filemode trustability check
and the config-set to record core.filemode should all be moved there
inside the "if (!reinit)" block.
All of the above assumes that the problem being solved is about what
happens when "git init" is run in an already functioning working
tree. If I misread what problem you are trying to solve, then none
of what I suggested in the above may apply.
