Thanks for your suggestions regarding my "Low-Level Linux Library for
Lua" ("L5") . The objective is really to include only low-level
stuff that cannot be written in Lua.
I agree that support for signals is one big missing item. Will look into it.
As you have noted, functions such as getpwnam, getpwuid, glob are
candidates for a Lua implementation. As such, they could also be nice
additions to the Lua part of L5 (see the l5 subdirectory).
I actually have an even lower-level project, VL5  which wraps the
Linux system call interface. This is more a toy - obviously a
dangerous one! - very ABI-dependant :-) I may also merge the syscall
interface into L5 some day.
Any additional comment, request, bug report are most welcome!! Feel
free to open an issue on the related github repositories
