From 00aa1d0c28de2895246a70c2beb09cd1e7e6cd13 Mon Sep 17 00:00:00 2001 From: Jesse Hathaway Date: Tue, 23 Oct 2007 16:56:43 -0400 Subject: add exposedroot option which exposes the root fs as ro This option allows you to expose the root read only. Using this option a person could upgrade the root filesystem or add packages without requiring the user to reboot. The root filesystem could be kept on an nfs volume or some other persistent medium. Multiple clients could then be booted off the same root fs. I used LTSP as a template to determine which directories to make rw. --- helpers/lh_chroot_hosts | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'helpers/lh_chroot_hosts') diff --git a/helpers/lh_chroot_hosts b/helpers/lh_chroot_hosts index c4d633e35..848038369 100755 --- a/helpers/lh_chroot_hosts +++ b/helpers/lh_chroot_hosts @@ -87,8 +87,9 @@ EOF # Restore hosts file mv chroot/etc/hosts.orig chroot/etc/hosts else - # Remove hosts file - rm -f chroot/etc/hosts + # Blank out hosts file, don't remove in case + # its a symlink, as in the case of exposedroot mode + cat /dev/null > chroot/etc/hosts fi # Removing stage file -- cgit v1.2.3
