Thank you @reldeiS

I've just discovered that this patch unlink the files in the 'live' directory of LE config dir, in particular:

• under the 'live' path there are symlinks to the archive directory, for continuity between updates
• the patch sed -i -e '$a\' /etc/letsencrypt/live/$(hostname)/cert.pem cause the unlink in the 'live' directory and the creation of a new file not linked to the one in the archive directory

@reldeiS : does this may breaks future updates of letsencrypt certificates ?

I can't recreate this on my machine in a quick test. The files created with the standard LE binary already have the eol, so the files are not changed.
I'll look into it.

@tomav I will change it the way Dominik suggested in #110. That way the LE created files are never touched and no unlinking should happen

Thanks for the fast update. Anyway for future reference the problem arise even in case EOLs are presents in the files, the problem being simply the use of the switch '-i' to sed itself.

yes i see where the problem was. On my host (Ubuntu 14.04) the links stay in tact.
However i fixed it in #118 by simply not changing the LE created *.pem files
