Description of problem:
During the leapp upgrade, customer reported the following issue:

Traceback (most recent call last):

As per the `ls -lR /etc/pki` output, the following relative symlinks are broken:

/etc/pki/pulp/content:
total 0
lrwxrwxrwx. 1 root root 36 May 29 2018 e097f848.r0 -> /var/lib/candlepin/candlepin-crl.crl
lrwxrwxrwx. 1 root root 20 May 29 2018 pulp-global-repo.ca -> /etc/pki/pulp/ca.crt

/etc/pki/tls/certs:
total 48
lrwxrwxrwx. 1 root root 29 May 15 2017 57dcc1cc.0 -> subscriptionrhsmredhatcom.pem

Version-Release number of selected component (if applicable):
leapp-repository-0.14.0-4.el7_9

How reproducible:
100%

Steps to Reproduce:

mkdir -p /etc/pki/pulp/content
cd /etc/pki/pulp/content
ln -s ../ca.crt pulp-global-repo.ca
ls /etc/pki/pulp/ca.crt
ls: cannot access /etc/pki/pulp/ca.crt: No such file or directory
leapp upgrade

Actual results:
Python traceback above

Expected results:
No traceback, content of /etc/pki copied into the "target userspace", possibly a check similar to the workaround I suggested (see below).

Additional info:

I'm unable to reproduce this issue with an absolute symlink like this one:
"e097f848.r0 -> /var/lib/candlepin/candlepin-crl.crl" (where the latter doesn't exist)
=> In this case, the upgrade is inhibited with "Upgrade requires links in root directory to be relative"
