permission question

[jumbohei]

Hi, I have a question regarding to the permission and much appreciated for inputs. Let’s say if a user A who writes a program and runs as a user and then he/she wants to take a snapshot and I don’t want to give this person the root access. Is that doable? If yes, can user A goes into the image and modify the UID to 0, which is as root, to restore and run that application as root? Thanks!

@jumbohei It might be worth looking at user namespaces. You can set UID=0 as follows:

$ id -u
1000
$ unshare -Umr bash
# id -u
0

I don’t want to give this person the root access. Is that doable?

Yes, checkpoint/restore can be used with non-root users as well: #1155
