Config file location not universal - hardcoded

[Manamama]

Affected Version

12.3.0

{I cannot use yay -V yet, as it does not run, so the version # is from this repository}

Describe the bug

Three bugs:

1. The compiler version was hard-coded somewhere in the main.go.
   Solution : commenting it out, works.

2. The Config directory is hardcoded in /yay/yay-12.3.0/config.go, the PacmanConf block, so:

yay --help
-> exit status 1
error: config file /etc/pacman.conf could not be read: No such file or directory
error parsing '/etc/pacman.conf'

(a read only location here, in Termux)
so it needs an easy fix:

func DefaultConfig(version string) *Configuration {
        return &Configuration{
                AURURL:                 "https://aur.archlinux.org",
                BuildDir:               os.ExpandEnv("$HOME/.cache/yay"),
                CleanAfter:             false,
                KeepSrc:                false,
                Editor:                 "",
                EditorFlags:            "",
                Devel:                  false,
                MakepkgBin:             "makepkg",
                MakepkgConf:            "",
                PacmanBin:              "pacman",
                PGPFetch:               true,
                PacmanConf:             "**$PREFIX/etc/pacman.conf**",
                GpgFlags:               "",
                MFlags:                 "",
                GitFlags:               "",
                BottomUp:               true,

                SudoLoop:               false,
                GitBin:                 "git",
                GpgBin:                 "gpg",
                SudoBin:                "sudo",
                SudoFlags:              "",
                TimeUpdate:             false,
                RequestSplitN:          150,
                ReDownload:             "no",
                ReBuild:                "no",
                BatchInstall:           false,
                AnswerClean:            "",
                AnswerDiff:             "",

Also works.

3. But afterwards it refuses to run.

./yay
error: operation blocked, you may not use pacman as root.
 -> error refreshing databases - exit status 1

I am not any root:

~/.../yay/yay-12.3.0 $ whoami
u0_a278
~/.../yay/yay-12.3.0 $ groups
u0_a278

See above

Reproduction Steps

1. Install
2. Bug 1
3. Recompile
4. Bug 2
5. Go to Step 4
6. Give up for a while

Expected behavior

Allowing me to install pamac, out of the box.

FYI, the bin way seems failing with repeated

etc

it works with default settings with most else:
