Re: [RFC PATCH 0/2] RFC: Implement deterministic uid/gid

[Mark Hatle <mark.hatle@windriver.com>]

I have updated the git://git.yoctoproject.org/poky-contrib mhatle/uidgid to the 
latest oe-core master.

I haven't seen any comments on this RFC yet.  Does anyone have any opinion 
either way on the code referenced here?

I'm confident patch 01/02 should be added to master.

The patch 02/02 works properly in all of my testing and does implement support 
for 'deterministic uid/gid' with dynamic passwd/group file construction during 
package install.  The code is only activated if USERADD_REWRITE_PARAMS is set to 
'1', so it's low risk -- but it does add a fairly large chunk of code to be 
maintained over time.
