Logging
To capture log into file with maximum log verbosity use these linuxrc params:
linuxrc.log=/tmp/linuxrc.log linuxrc.debug=4
Testing the Installation
A regular SUSE installation DVD gets built via linuxrc.rpm, then installation-images.rpm, then a KIWI image build.
For testing a shortcut is available: mksusecd (GitHub, OBS).
Use:
mksusecd --initrd ./linuxrc.rpm ...or, without an RPM:
make
mkdir /tmp/initrd
cp linuxrc /tmp/initrd/init
mksusecd --initrd /tmp/initrd ...You may also use mksusecd --micro in case you only want to test Stage 1
and not a full install.
openSUSE Development
The package is automatically submitted from the master branch to
system:install:head
OBS project. From that place it is forwarded to
openSUSE Factory.
