Running the setup script on a barebones Ubuntu (both Focal and Jammy), close to the end there is a 30 secs wait while the script tries to start php-fpm, and fails.

The output is: Starting php-fpm ................................... failed

By the looks of it, it seems that the php-fpm service script which gets installed in init.d has a problem with the pid file not being found. I am not sure if this is due to the pid file being specified in the fpm config file which is generated during the setup, if the php-fpm binary simply disobeys the cli option with the name of the pid file to generate, or if it is a filesystem permissions issue.

This does not prevent using the installed php, nor php-fpm, as the php-fpm process will actually work.

It just makes the setup process slower than it could be.

This is just a nitpick, but: trying to run the setup script on a barebones Ubuntu, both with Jammy and Focal, there is an error during the setup:

ln: failed to create symbolic link '/usr/include/php/20XXYYZZ': No such file or directory

I think it would be enough to create the dir '/usr/include/php' to fix that

The dependencies listed at the bottom of the readme could be made more clear by listing the exact ubuntu packages required, at least on a stock ubuntu. Atm it is not very clear which of the requirements is an actual package to install, and which one is not.

This is the minimal list of packages I needed to install, on a 'plain' ubuntu Jammy container, in order to get the built php to run:

 DEBIAN_FRONTEND=noninteractive apt-get install -y \
            curl \
            enchant-2 \
            imagemagick \
            libc-client2007e \
            libcurl3-gnutls \
            libmcrypt4 \
            libodbc1 \
            libpq5 \
            libqdbm14 \
            libtinfo5 \
            libxpm4 \
            libxslt1.1 \
            mysql-common \
            sudo \
            zstd

On Focal, enchant-2 has to be replaced by enchant
