The failure of pear was because of the "noexec" option on /tmp rather than its being readonly. In fact, it's not readonly as you were able to move directories around and make symbolic links. Those actions would have failed if the /tmp drive was readonly. Specifically, the line: /usr/local/bin/phpize: /tmp/pear/temp/xdebug/build/shtool: /bin/sh: bad interpreter: Permission denied ...is what happens when you try to exec a script anywhere under /tmp when it's mounted with the "noexec" option. % mount -oremount,exec /tmp % pecl install xdebug % mount -oremount,noexec /tmp Also - its good practice to lock /tmp back down after changing the option so pecl will work. Best regards, -pbr Almost. The failure of pear was because of the “noexec” option on /tmp rather than its being readonly.

Specifically, the line:

…is what happens when you try to exec a script anywhere under /tmp when it’s mounted with the “noexec” option.

% mount -oremount,exec /tmp
% pecl install xdebug
% mount -oremount,noexec /tmp

Also – its good practice to lock /tmp back down after changing the option so pecl will work.
