Dear Opam Team, first let me say that I am using the Cygwin MinGW cross opam from https://fdopen.github.io/opam-repository-mingw/installation/. I have the call to .opam/opam-init/init.sh in my .bach_profile file. I observe two obscurities with this setup: 1.) It is really hard to get rid of the opam path settings, I guess cause of the environment hook installed. E.g. although opam env -revert displays the correct original "pre opam" PATH, evaluating with eval $(opam env -revert) does not have the desired effect - the PATH is exactly as before. I guess the environment hook immediately sets it back it. How can I temporarily get back to my original PATH? 2.) Apparently the MANPATH gets longer each time I execute a command in bash. E.g. when I do a few times "echo $MANPATH | wc" the length displayed by wc increases each time (by one additional reference to the opam man path). This is unfortunate because the total environment of a process is quite limited under Cygwin/windows (I think to 8k). Is this specific to the MinGW cross opam or is this a general problem? Do others have the call to .opam/opam-init/init.sh in there profile or a simple eval $(opam env)? What is the advantage of this rather invasive hook?
