Hi Juanito,
mdadm.tcz is in the tc-11.x x86_64 repo, but the current date in tinycore apps 11 is "2017/01/11" and the changelog is "first version" by you . It works partially in tc-11, but with a mistake.
linux-kernel-sources-env from tc-10.x doensn' t work in tc-11. cliorx linux-kernel-sources-env.sh can't find the source.
Can you help ?
Ricky
