WARNING:
|
|
|
|
This is a "lazy" migration: Ubuntu init scripts are migrated
|
|
similar, but not identical. Some services have been skipped, because
|
|
they are not necessary with cinit or in general.
|
|
|
|
Check /etc/cinit before rebooting with cinit!
|
|
|
|
KNOWN BUGS:
|
|
|
|
S20checkroot.sh: Only / is being fscked, other partitions are ignored.
|
|
|
|
HINT:
|
|
|
|
Make sure init=/sbin/cinit is set in your bootloader.
