## instructions
I tend to break and rebuild my systems regularly.  It has gotten to the point that I generally do not have an SSH key for over a year.

This has created a serious dilemma when it comes to maintaining access to remote systems.  I usually disable normal password access on any servers I maintain, which means unless I have multiple systems that can access so I can replace the keys I could permanently loose access to those systems.  In considering possible solutions I came up with one that has saved my bacon regularly.

First, I use my [dot-files](https://github.com/cdelorme/dot-files) repository after installing any new system.  If that system is secure I will generate a new SSH key and load it into github via curl through their api.

On servers which I need to retain access, I create a simple bash script to poll my github accounts keys.  I throw it into a user-local `~/.bin/update-keys` file, and make it executable.

Finally, I modify the crontab to execute this script regularly:

## se_srpm_version.sh
#!/bin/bash

# This script add git commit info in spec `Release`
# https://fedoraproject.org/wiki/Archive:Tools/RPM/VersionComparison?rd=Tools/RPM/VersionComparison
#
# eg.
# (1)
#  prev version (tag) 1.5
#  new version still 1.5 but we want to modify the spec
#    * don't change any version (version/ release)
