   Maybe is a tmpfs? For example in Centos-RedHat distros /var is a tmpfs and most people tend to put the cache directory here.
   At the start, the directory is owned by root, so pagesped can´t read/write.
   This can be solved creating a conf file in /etc/tmpfiles.d (call it pagespeed-cache.conf) with some lines like:
   ```
   D /var/path-to-cache-directory/ 0755 pagespeed-user:pagespeed-group -
   f /var/path-to-cache-directory/!clean!time! 0755 pagespeed-user:pagespeed-group -
   
   ```
   These 2 lines creates the directory (D) and the file (f) in these paths, permisions and owner at system start, before any process acces it.
   Note the last -, it is needed.
   More on this here: https://man7.org/linux/man-pages/man5/tmpfiles.d.5.html
   
   I don´t know if Ubuntu or other distros has this feature.
