      On Alix, on the console during boot, I get:

      Mounting filesystems...
      [: -gt: unexpected operator
      [: -gt: unexpected operator
      Setting up memory disks... done.[/code]
      I think that spits out of rc.embedded when use_mfs_tmp_size and use_mfs_var_size have not been set in the config.
      It still falls through the tests somehow and ends up with the default 40MB and 60MB memory disks.
      

      As the Greek philosopher Isosceles used to say, "There are 3 sides to every triangle."

        I think that's the bug I fixed with the commit I linked, make sure you've got that one (or try another snap after)
        
        The problem was the config slice wasn't mounted when it tried to read the config, so the file wasn't there. The command should always get a number back from grep -c so long as the file exists, but I could add some extra protections just in case.

          It needs a bit fancier checking for null values in rc.embedded - I just submitted a pull request. You might have a neater way of making it do the "-gt 0" check against a possibly empty variable.

                Installed the latest snapshot, turned on this feature. Left blank for default space. Installed Squid3 and after reboot it gives me the below error on the login page and I am locked out as I cannot log into the system. The pfSense is a remote box and I don't have physical access to it. Darn !

                Warning: session_start(): open(/var/tmp//sess_a5f98c219d39beb8a18480d9a81a2024, O_RDWR) failed: No space left on device (28) in /etc/inc/auth.inc on line 1316

                  Well what did you expect when you gave it a pittance for space in /tmp and /var and tried to install a package that used it all up?

                  Unfortunately there is no way to prevent foot-shooting there, but I suppose I could add even more stern warnings to the page.

                    I realized about the setting just the second after I clicked reboot. Any backdoor method to gain access to the system?

                      Hard to say for sure, if you can get it to the console menu at all you might be able to go back to an older version of the config, assuming any are there. It very well could have wiped out quite a bit if /tmp and/or /var filled up.

                      If you can get to a prompt, check /conf/backup/ and see if there are any old configs there, if there are, then copy one to /conf/config.xml, rm /tmp/config.cache, and reboot

                        Can't do much remotely. Only access I had to it was over WAN https.

                          Updated to the latest snapshot via automatic update. No option in System-Advanced-Mics.
                          What am I doing wrong?

                            is it possible to create a option for a third RamDisk?
                            So we can choose Squid/HAVP/etc for using this space for caching!
                            so the normal usage ofย  /tmp and /var is not affected?!

                              On nanobsd, the checkbox "Use memory file system for /tmp and /var" does not appear, because it is not optional - it always "Uses memory file system for /tmp and /var".

                                No, there is no option for that, and probably won't be. Not something common enough to warrant doing. Just config squid to use more memory cache and not a disk cache in a RAM disk. That's a discussion for a different thread though.

                                    You must have some other issue preventing that page from getting updated, but it's not relevant to this thread. Start a fresh thread and someone can help you investigate why a firmware update isn't updating that file.

                                      The missing items are all down the end and are all items that have been added in March 2013. My nanobsd system shows them all - Skip rules when gateway is down, /tmp RAM Disk Size, /var RAM Disk Size, Periodic RRD Backup, Periodic DHCP Leases Backup.
                                      It is just as if your /usr/local/www/system_advanced_misc.php was never updated. On your system, check if that file actually contains code for any of these items. Then as JimP recommends, start another thread to try and sort out what happened during updating.

                                        OK. Now I got this option activated. On reboot I see next (see image)
                                        Any comments?

                                          Hard to say exactly. I didn't see that in any of my testing. How large did you try to set the /tmp and /var disks to be? perhaps it used all your memory?

                                            2GB of memory installed. 18xxMB free.
                                            First time I have used 512MB for both RAM disks and now I left it blank, when screenshot is taken.
