I have identified asbestos in both Putty and rubberised sealants
Putty should not be allowed to dry completely. If it does, then it will become brittle and may shrink and crack. The main purpose of putty is to form a seal between the glass and the wooden window frame. The putty should be painted to seal in the linseed oil which keeps it pliable. A film of hard putty on the surface forms after 2 to 3 weeks (weather dependent) and then the painting should be carried out to stop any further drying of the putty.

In general, no, it is not difficult at all. As long as you stick to the POSIX (and other open standards) and use a conformant compiler for the software there shouldn't be any problem in porting software. I do it all the time - from Linux to Unix, or Unix to Linux, makes no difference. In fact, a lot of common software is cognizant of the actual Operating System at compile time and will take care of the differences (if there are any).
