I noticed in the strace calls for useradd that the kernel is returning the correct count of directories, but the useradd is clearly not copying all of them. Below is the strace output.

Title:
useradd command does not copy all of /etc/skel
Status in shadow package in Ubuntu:
New
Bug description:
====================================================
I know the useradd command is discouraged, but I wanted to report the bug to make the maintainers of the package aware.
Recently there was an update of Ubuntu's passwd package which is
sourced from shadow from version 4.8.1-1ubuntu5.20.04.2 to version
4.8.1-1ubuntu5.20.04.3
When using the useradd command, the /etc/skel directory with contents
below, an only copies in one empty folder.

I noticed in the strace calls for useradd that the kernel is returning the correct count of directories, but the useradd is clearly not copying all of them. Below is the strace output.
