How did you add the new user account?  You added it in the
‘operating-system’ declaration and then run ‘guix system reconfigure’,
right?

Could it be that /home is on a separate partition?  There’s a problem
when that is the case: .

When i try to login such as tron does not allow login and slim 
restart.


i check secure and slim.log log files, this message appears in 
slim.log:


slim: pam_authentication(): User not known to the underlying
authentication module

The solution to fix this issue was: changing the owner:group for the
home user.

i replace bob user with tron in the configuration file, and later i 
reconfigure. And i have only root partition.


Thanks

cd /home
chown -Rf 30019:users tron


If I am reading this correctly, it means that you changed ownership of
all files in /home to the "tron" user. In general that seems like a bad
idea. What about other users?



and works.






In the new generations the user are created but do not enter.

Thanks

bug#22514: emacs INFO pages have "?"s instead of "'"s

Note/clarification: the problem is only with user accounts. root emacs
INFO "'" quotes are normal and 'echo $LANG' returns "en_US.UTF-8".

bug#22533: Non-determinism in python-3 ".pyc" bytecode

[Leo Famulari]

While preparing a package for borg [0], I found that the built output
was not reproducible. The problem is that the bytecode compiler [1] for
Python 3.4.3 (our current version) encodes the mtime of the
corresponding Python source file in the output. This is described in
PEP-3147 [2], and the responsible Python code is referenced below [3].

I tested a few of our existing python-3 packages: python-ccm,
python-pysam, and python-scripttest all exhibit the same problem.

We fixed this in python-2 with the patch
python-2.7-source-date-epoch.patch, but I don't know how to write this
patch for python-3.

Can somebody write this patch?

I asked about this on #debian-reproducible and they said that it wasn't
an issue for Debian since they don't ship bytecode, but instead generate
it at install time. Of course, that doesn't really apply to Guix.

I used diffoscope-34 to inspect the build outputs to find this, and you
can see the report here:
https://famulari.name/misc/7c55c9e97f668234ddea50299d986f14/borg-diffoscope-report.html

It's first demonstrated in the file
...-borg-0.30.0/lib/python3.4/site-packages/__pycache__/site.cpython-34.pyc.

The first 2 bytes are the "magic numbers" described in PEP-3147, which
specify the version of the bytecode format. The next 2 bytes are the
problematic timestamp, as described in the PEP-3147.
