From 2d6e71e8d2d6f61f109566ff3148d3b1aa50c68c Mon Sep 17 00:00:00 2001 From: Adam Williamson Date: Tue, 20 Aug 2019 15:39:04 -0700 Subject: [PATCH] Allow special value 'once' for PXEBOOT, to PXE boot...once For a PXE install test, we want to boot PXE just the *first* time, then revert to default boot order (much like we boot once=d by default for optical media installs). This allows the special value 'once' for the PXEBOOT var to request this.
