/* !!! WARNING !!!
|
||
|
|
** This is highley experimental! Do NOT run it unless you know what you are doing!
|
||
|
|
** You can serious screaw things up!
|
||
|
|
**
|
||
|
|
** Requirements:
|
||
|
|
** - Must be run as root
|
||
|
|
** - You need to have RAM disk support complied into the kernel
|
||
|
|
** - You have to have the CGI binary for PHP
|
||
|
|
** - This ONLY works with Linux
|
||
|
|
** - The 2.2 kernel is limited to 20 RAM disks, so you will have to cut down on what you copy over
|
||
|
|
** - I wouldn't run this on a server with less then 196 MB of RAM. If it has less, preformance
|
||
|
|
** will only decrease. Since proccess will need to swap out to disk.
|
||
|
|
**
|
||
|
|
** The phpGroupWare development team does not support this program in anyway. If it breaks
|
||
|
|
** or messes up your system, don't email us. Don't submit bug reports. If you do find ways to make
|
||
|
|
** it better, please submit patches directly to me. jengo@phpgroupware.org
