Could I please get couple of reviews for the following
bug fix:
7010191 After installing from LiveCD, the machine fails during rebooting, mount
errors
Webrev:
http://cr.opensolaris.org/~aalok/7010191/
Background:
Due to the way /dev/null was being opened by the generate_gnome_caches
method of the pre-pkg-img-mod checkpoint, an empty file by that name
was being left over in the pkg_image area. This file was then getting
transferred to the installed system which subsequently caused havoc
during boot.
The old DC would create /dev/null as part of
slimcd_pre_boot_archive_pkg_img_mod in the following way:
echo "dev/null" | ($CD / ; $CPIO -Lp $PKG_IMG_PATH)
This resulted in the creation of a character special device named /dev/null
in the package image area.
New DC was effectively doing something similar with the exception of
not doing it quite correctly. Turns out a special device named /dev/null
in the pkg_image area isn't needed afterall, a flat file named /dev/null
suffices just as well.
The proposed fix creates a temporary flat file named /dev/null.
Testing:
Ensured that the LiveCD images build, boot, Install and reboot
after install correctly. Also ran DC unittests to make sure there
are no regressions.
Thanks,
Alok
