Description

Coming soon (or later)... This package is tracing its own steps during installation/upgrade/removal, for learning purpose... Each step being one of the scripts: start-stop-status, preinst, postinst, preupgrade, postupgrade, preuninst, postuninst

Ex.:

1. For an installation, with variable $SYNOPKG_PKG_STATUS = "INSTALL"

• the new installation wizard
• the new preinst in the temp /volume1/@tmp/pkginstall/scripts
• the new postinst now ready in /var/packages/[package name]/scripts
• the new start-stop-status 'log' in /var/packages/[package name]/scripts (Could possibly be called later)
• the new start-stop-status 'status' in /var/packages/[package name]/scripts
• the new start-stop-status 'start' in /var/packages/[package name]/scripts

2. For an Upgrade, with variable $SYNOPKG_PKG_STATUS = "UPGRADE"

• the new upgrade wizard
• the old start-stop-status 'stop' still in /var/packages/[package name]/scripts
• the new preupgrade in the temp /volume1/@tmp/pkginstall/scripts
• the old preuninst still in /var/packages/[package name]/scripts
• the old postuninst still in /var/packages/[package name]/scripts
• the new preinst in the temp /volume1/@tmp/pkginstall/scripts
• the new postinst now ready in /var/packages/[package name]/scripts
• the new postupgrade in /var/packages/[package name]/scripts
• the new start-stop-status 'log' already in /var/packages/[package name]/scripts (Could possibly be called later)
• the new start-stop-status 'status' already in /var/packages/[package name]/scripts
• the new start-stop-status 'start' already in /var/packages/[package name]/scripts

3. For an Uninstallation, with variable $SYNOPKG_PKG_STATUS="UNINSTALL"

• the old uninstallation wizard
• the old start-stop-status 'stop' still in /var/packages/[package name]/scripts
• the old preuninst still in /var/packages/[package name]/scripts
• the old postuninst still in /var/packages/[package name]/scripts

• /usr/syno/etc/packages/[package name]/ is created if it does not exist. It is not deleted automatically and can be used to keep files between installations or during upgrades.
• /volume1/@appstore/[package name]/ is created to deploy the application contained in the package. It is deleted during an upgrade or by the uninstallation.
• /usr/syno/synoman/webman/3rdparty/[package name] -> /volume1/@appstore/[package name]/target/[dmsuidir]/ is created during installation and removed after uninstallation.
• /var/packages/[package name]/ is the folder where the package is installed (with its scripts, wizards, etc...)
