Recently when cygwin setup runs windows 10 started creating

Turned out that the culprit is the
/etc/postinstall/zp_man-db-update-index.dash script which runs at the
end of every setup session, although I couldn't figure why: it just
runs mandb with some fancy redirection and nothing untoward happens
when it is run manually and with admin privileges, but the folder in
question was never created until I ran mandb to create man index which
for some reason was not created automatically during installation, and
when /var/cache/man/index.db is removed which effectively disables
this script this folder is not created. I am baffled.
Me too. Apparently this is some bug deep in the bowels of Windows that
triggers when neither SystemDrive nor ProgramData are defined in the
environment and a new console session gets created. It seems I can work
around getting the extra directories created by defining SystemDrive in
a certain nonsensical way, but it really is an ugly hack; I'll have to
see if there's a better fix.
Problem mentioned by me some time ago, may be related to this, from
undocumented mandb handling of Windows localization catalog folders:

which may include moving "stray cats" (also undocumented) to / [Cygwin]
root so they get noticed and handled?
