So: patch-chrome_browser_chrome__browser appears to be a
truncated: patch-chrome_browser_chrome__browser__main__posix.cc
file name and find also gets the same oddity.

(Note: This had /usr/ports in a main context and /mnt/
referring to a release/13.0.0 context.)

Do you want a debug kernel to be used? Do you have a preference
for main vs. stable/13 vs. release/13.0.0 based? Is it okay to
stick to the base version things are now based on --or do you
want me to update to more recent? (That last only applies if
main or stable/13 is to be put to use.)
