I'm trying to understand the OTA process; as I understand, after fetching the files, an Upgrader is launched from the recovery image to update the phone's partitions ... what I do not understand is the folliwing example: I fetched the OTA-6 files for my device/channel which are: $ ls custom-996a0631cdd3014deb88bfa3c228a70922d68ea953607e3133d94713b351f650.tar.xz device-169bc102d21754e91d142385ffadb32b63cfa92831b82f221b5f38d9bc65b687.tar.xz ubuntu-59b0c7aa8af63dda3a06005a6087c1faa4ed8993321293b276e7f7021d0cb0a3.tar.xz version-25.tar.xz when I now look for two example files in the tar files: $ tar xzf ubuntu-59b0c7aa8af63dda3a06005a6087c1faa4ed8993321293b276e7f7021d0cb0a3.tar.xz system/etc/apparmor.d/local/usr.lib.telepathy^C $ tar xzf ubuntu-59b0c7aa8af63dda3a06005a6087c1faa4ed8993321293b276e7f7021d0cb0a3.tar.xz system/etc/apparmor.d/cache/usr.lib.telepathy^C $ ls -l system/etc/apparmor.d/*/usr.lib.telepathy -rw------- 1 guru wheel 200656 25 ago 19:39 system/etc/apparmor.d/cache/usr.lib.telepathy -rw-r--r-- 1 guru wheel 124 25 ago 19:35 system/etc/apparmor.d/local/usr.lib.telepathy $ md5 system/etc/apparmor.d/*/usr.lib.telepathy MD5 (system/etc/apparmor.d/cache/usr.lib.telepathy) = 6681f89d5dd73d76580000f2035722d5 MD5 (system/etc/apparmor.d/local/usr.lib.telepathy) = dd65bcf98ff23b7c811d0380b5d6947f i.e. both above files have last mod time as 25 ago ... When I now look into my device which was updated on September 13, around 7.20am I see: phablet@ubuntu-phablet:~$ ls -l /etc/apparmor.d/cache/usr.lib.telepathy /etc/apparmor.d/local/usr.lib.telepathy -rw------- 1 root root 200656 sep 13 07:21 /etc/apparmor.d/cache/usr.lib.telepathy -rw-r--r-- 1 root root 124 ene 29 2015 /etc/apparmor.d/local/usr.lib.telepathy phablet@ubuntu-phablet:~$ sudo md5sum /etc/apparmor.d/*/usr.lib.telepathy 6681f89d5dd73d76580000f2035722d5 /etc/apparmor.d/cache/usr.lib.telepathy dd65bcf98ff23b7c811d0380b5d6947f /etc/apparmor.d/local/usr.lib.telepathy i.e. only one file was really updated, the other not. Why not both in this example? What decides if a give file on the device will be renewed or not? matthias -- Matthias Apitz, ✉ [email protected], 🌐 http://www.unixarea.de/ ☎ +49-176-38902045 No!
