Subject: * with-creds: use /dev/shm for ccaches if exists, fall back to /tmp
X-Git-Tag: 1.6~12
X-Git-Url: https://git.michaelhowe.org/gitweb/?a=commitdiff_plain;h=3ceebf92ad3acdbda6d53a0fd5e9d87c50029c58;p=packages%2Fm%2Fmh-sysadmin-tools.git

* with-creds: use /dev/shm for ccaches if exists, fall back to /tmp
  otherwise.  This solves the issue of NFS picking the wrong credentials to
  identify the user.
* with-creds: set -e so failures cause it to stop
