Strange permissions on /etc /usr with uid 1005 and gid 1006

Ubuntu Touch is not a regular GNU/L distrib.
It's designed for smartphones and mobile devices (android native one at first), with system files read only and some other particularities.
This for user security reasons (this OS is for any users, like me, not only power linux users). -

Thanks, I mark the thread solved
I'm lucky that i had a backup made with rsync so I had the correct permissions to restore
Just another question: is possible to download somewhere the system.img untouched for Ubuntu touch for Nexus5? -
P pelenze has marked this topic as solved on

@pelenze
You can use ubports installer any time to reinstall your N5.
When doing so, you can choose to keep user data, or erase it, by ticking or not the "wipe user data" (or so) option.There is a way to retrieve "img" files for your device in the process, but can't tell how exactly (stored in a temp folder).
But not really necessary as ubports installer is the way to install on N5.
You can also retrieve "raw" files on ubports git, but then you'll need to compile (is this the right word?) those.

@pelenze Yeah I would not bother with manual steps, just reinstall. All data is saved, if you do not check the wipe option. We use readonly rootfs for a reason, so that we can quickly exchange it. Also its nice to have it against any malicious attacks that otherwise could render your device unbootable

I understand your advice to be careful but on my BQ E5 OTA-22 I notice that most of the folders in / are 755 root root. It is the same for /var/lib/lxc/android
Why should it be different on N5?

@pulsar33 Because we use different builders for the root files system since Halium 9 I think

There is no need to reinstall, I had restored original perms copying them from the backup files(thanks rsync).
Only one question: on your phones this file exist?/android/cache/legacy_channel -
@pelenze
Not on my MX4
Edit :
Neither on my N5

@keneda
Thanks -
@pelenze Please keep that, its a flag that you are on an older device that needs special treatment during upgrades. Removing this can brick your device when you are switching between channels or if we update to a newer Halium version.

@flohack
Thanks I will not remove, but I notice after change permission the first time that the file was removed..and not by me(probably an upgrade).
I have restored it from backup and give it the right permissions. -
@flohack
What ?
Should i have this file on MX4 or N5 ?
I did not remove any file. -
