PM Software Stack
PMSS, short of PM Software Stack is a compilation of scripts to manage single server side seedbox configuration, turning instantly and conveniently an regular Debian 7.0 server into a seedbox. The PMSS does not contain multi-server management utilities nor clustering support out-of-box, but does include PM Master GUI automatic remote update features. Debian 7 support is considered stable, Debian 8 support is considered testing/unstable.

Debian 8 notes
Debian 8 all the basics pretty much work, but things keep breaking up randomly. Debian has had maintainer changes most apparently and there is differences in philosophies which makes some things rather complicated, and only partially working. Most severe is probably the changes how block devices are handled which causes servers not to boot, where as a Debian 7 server would boot without an issue.
Other issues include complete revamp on OpenVPN config (old configs do not function at all), /var/run/pmss keeps disappearing after install for unknown reason causing traffic metering and other issues. Runlevel/init script issues causing lighttpd to launch as system daemon and several others. git will not sometimes install, despite same command installs znc and znc installs, and other weirdness with apt. apt itself should almost be considered unstable at this point, sometimes packages simply will not install.
We recommend sticking with Debian 7 for now unless you really really need acd_cli, newer kernel or other advancements of Debian 8
- cron/cpuStat.php: Collect CPU usage stats, user, nice, sys and idle for 2mins. Saves to /var/run and http publicly fetchable serialized output
- config/root.cron: Add cpuStat to run every 15mins, after 45sec delay (avoid other scheduled cronjobs this way)
- util/update-step2.php: Hack for nzbdrone & mono to get them installed on a Debian 8 system

- util/userTrafficLimit.php: Same thing as above

- update-step2: separate setup apt sources.list.d/sonarr.list. This also means Sonarr will now update normally.
- createNginxConfig.php: Now always run lighttpd config. This is a bug fix, where manually changed lighttpd port would eventually mismatch on nginx
- configureLighttpd.php: Increased potential port range.
- skel/.lighttpd/custom: Empty file created to avoid warnings. This is where users can input their custom lighttpd settings if they need some.

- userTransfer.php: Decreased the time for re-attempting user migration
- recreateUser.php: Also copy htpasswd file from old version
- (GUI) Change welcome page quota display to use Kibibyte format to avoid confusion.
A privileged user could use an internet download manager to basicly DOS the server with huge amount of threads trying to download large files (gigs in size), with sufficient thread quantity eventually linux kernel couldn't schedule any I/O time for disk nor ram for essential applications such as SSH. This could not be done by unprivileged user since requirement is very large file sizes. This would lead to a race condition as nginx wants to cache as fast as possible, hence "downloading" from user lighttpd process as fast as possible, which results in heavy RAM consumption and 'especially' heavy disk I/O activity - with sufficient threads scheduling breaks down.
