Package Filesystem Hierarchy Standard

After the package installed, there will be some directories for package to put their data. There will be different directories linked for packages who installed on volume partition / system partition.

/var/packages/[package_name]
├── etc     -> /volume[volume_number]/@appconf/[package_name] (move to volume since 7.0-41330, and old path still works)
├── var     -> /volume[volume_number]/@appdata/[package_name]
├── tmp     -> /volume[volume_number]/@apptemp/[package_name]
├── home    -> /volume[volume_number]/@apphome/[package_name]
└── target  -> /volume[volume_number]/@appstore/[package_name]

/var/packages/[package_name]
├── etc     -> /usr/syno/etc/packages/[package_name]
├── var     -> /usr/local/packages/@appdata/[package_name]
├── tmp     -> /usr/local/packages/@apptemp/[package_name]
├── home    -> /usr/local/packages/@apphome/[package_name]
└── target  -> /usr/local/packages/@appstore/[package_name]

Please refer to install_type in INFO for more information about installation on volume / system partition.
