  54 You appear to have disabled jailsetup which is perfectly fine for installations
  55 that will not be using an ssh jail.  However, in that case, running the install
  56 process as the superuser is highly discouraged.
  57
  58 Instead, running it as the configured $Girocco::Config::mirror_user is much
  59 preferred.
  60
  61 The install process will now pause for 10 seconds to give you a chance to abort
  62 it before continuing to install a disable_jailsetup config as the superuser.

 312 2.6.x prior to 2.6.6 and 2.7.x prior to 2.7.4.
 313
 314 Besides the security fixes included in later versions, versions prior to
 315 2.2.0 may accidentally prune unreachable loose objects earlier than
 316 intended.  Since Git version 2.4.11 is the minimum version to include all
 317 security fixes to date, it should be considered the absolute minimum
 318 version of Git to use when running Girocco.
 319
 320 This is not enforced, but Git is easy to build from the git.git submodule
 321 and upgrading to GIT VERSION 2.4.11 OR LATER IS HIGHLY RECOMMENDED.
